AMR 1.8.1.9012as.rsi(). EUCAST 2022 is now the new default guideline for all MIC and disks diffusion interpretations.as.rsi() on certain EUCAST breakpoints for MIC valuesas.integer() for MIC values, since MIC are not integer values and running table() on MIC values consequently failed for not being able to retrieve the level position (as that’s how normally as.integer() on factors work)droplevels() on MIC will now return a common factor at default and will lose the <mic> class. Use droplevels(..., as.mic = TRUE) to keep the <mic> class.ab_from_text()
set_mo_source(), which now also allows the source file to contain valid taxonomic names instead of only valid microorganism ID of this packagerandom_*() function (such as random_mic()) is now possible by directly calling the package without loading it first: AMR::random_mic(10)
prevalence of the microorganisms data set from 3 to 2 for these genera: Acholeplasma, Alistipes, Alloprevotella, Bergeyella, Borrelia, Brachyspira, Butyricimonas, Cetobacterium, Chlamydia, Chlamydophila, Deinococcus, Dysgonomonas, Elizabethkingia, Empedobacter, Haloarcula, Halobacterium, Halococcus, Myroides, Odoribacter, Ornithobacterium, Parabacteroides, Pedobacter, Phocaeicola, Porphyromonas, Riemerella, Sphingobacterium, Streptobacillus, Tenacibaculum, Terrimonas, Victivallis, Wautersiella, Weeksella
AMR 1.8.12022-03-24Fix for using as.rsi() on values containing capped values (such as >=), sometimes leading to NA
Support for antibiotic interpretations of the MIPS laboratory system: "U" for S (‘susceptible urine’), "D" for I (‘susceptible dose-dependent’)
Improved algorithm of as.mo(), especially for ignoring non-taxonomic text, such as:
mo_name("methicillin-resistant S. aureus (MRSA)")
#> [1] "Staphylococcus aureus"More informative warning messages
Added 192 as valid MIC
Updated MIC printing in tibbles
Increased speed for loading the package
AMR 1.8.02022-01-07p_symbol() and all filter_*() functions (except for filter_first_isolate()), which were all deprecated in a previous package versionkey_antibiotics() and key_antibiotics_equal() functions, which were deprecated and superseded by key_antimicrobials() and antimicrobials_equal()
ggplot2::ggplot() generics for classes <mic>, <disk>, <rsi> and <resistance_predict> as they did not follow the ggplot2 logic. They were replaced with ggplot2::autoplot() generics.get_locale() to get_AMR_locale() to prevent conflicts with other packagesSupport for the CLSI 2021 guideline for interpreting MIC/disk diffusion values, which are incorporated in the rsi_translation data set. This data set now more strictly follows the WHONET software as well.
Support for EUCAST Intrinsic Resistance and Unusual Phenotypes v3.3 (October 2021). This is now the default EUCAST guideline in the package (all older guidelines are still available) for eucast_rules(), mo_is_intrinsic_resistant() and mdro(). The intrinsic_resistant data set was also updated accordingly.
Support for all antimicrobial drug (group) names and colloquial microorganism names in Danish, Dutch, English, French, German, Italian, Portuguese, Russian, Spanish and Swedish
Function set_ab_names() to rename data set columns that resemble antimicrobial drugs. This allows for quickly renaming columns to official names, ATC codes, etc. Its second argument can be a tidyverse way of selecting:
example_isolates %>% set_ab_names(where(is.rsi))
example_isolates %>% set_ab_names(AMC:GEN, property = "atc")Function ab_ddd_units() to get units of DDDs (daily defined doses), deprecating the use of ab_ddd(..., units = TRUE) to be more consistent in data types of function output
antibiotics data set now contains all ATC codes that are available through the WHOCC website, regardless of drugs being present in more than one ATC group. This means that:
antibiotics$atc is now a list containing character vectors, and this atc column was moved to the 5th position of the antibiotics data setab_atc() does not always return a character vector of length 1, and returns a list if the input is larger than length 1ab_info() has a slightly different outputThey now also work in R-3.0 and R-3.1, supporting every version of R since 2013 like the rest of the package
Added more selectors for antibiotic classes: aminopenicillins(), antifungals(), antimycobacterials(), lincosamides(), lipoglycopeptides(), polymyxins(), quinolones(), streptogramins(), trimethoprims() and ureidopenicillins()
Added specific selectors for certain types for treatment: administrable_per_os() and administrable_iv(), which are based on available Defined Daily Doses (DDDs), as defined by the WHOCC. These are ideal for e.g. analysing pathogens in primary care where IV treatment is not an option. They can be combined with other AB selectors, e.g. to select penicillins that are only administrable per os (i.e., orally):
example_isolates[, penicillins() & administrable_per_os()] # base R
example_isolates %>% select(penicillins() & administrable_per_os()) # dplyrAdded the selector ab_selector(), which accepts a filter to be used internally on the antibiotics data set, yielding great flexibility on drug properties, such as selecting antibiotic columns with an oral DDD of at least 1 gram:
example_isolates[, ab_selector(oral_ddd > 1 & oral_units == "g")] # base R
example_isolates %>% select(ab_selector(oral_ddd > 1 & oral_units == "g")) # dplyrAdded the selector not_intrinsic_resistant(), which only keeps antibiotic columns that are not intrinsic resistant for all microorganisms in a data set, based on the latest EUCAST guideline on intrinsic resistance. For example, if a data set contains only microorganism codes or names of E. coli and K. pneumoniae and contains a column “vancomycin”, this column will be removed (or rather, unselected) using this function.
Added argument only_treatable, which defaults to TRUE and will exclude drugs that are only for laboratory tests and not for treating patients (such as imipenem/EDTA and gentamicin-high)
Fix for using selectors multiple times in one call (e.g., using them in dplyr::filter() and immediately after in dplyr::select())
Fix for using having multiple columns that are coerced to the same antibiotic agent
Fixed for using all() or any() on antibiotic selectors in an R Markdown file
mo_gramstain()) determination of the taxonomic class Negativicutes within the phylum of Firmicutes - they were considered Gram-positives because of their phylum but are actually Gram-negative.

For this reason, this column is now numeric instead of a character, and mo_url() has been updated to reflect this change.get_episode() and is_new_episode()
get_episode() and is_new_episode() can now cope with NAsAll antibiotic class selectors (such as carbapenems(), aminoglycosides()) can now be used for filtering as well, making all their accompanying filter_*() functions redundant (such as filter_carbapenems(), filter_aminoglycosides()). These functions are now deprecated and will be removed in a next release. Examples of how the selectors can be used for filtering:
# select columns with results for carbapenems
example_isolates[, carbapenems()] # base R
example_isolates %>% select(carbapenems()) # dplyr
# filter rows for resistance in any carbapenem
example_isolates[any(carbapenems() == "R"), ] # base R
example_isolates %>% filter(any(carbapenems() == "R")) # dplyr
example_isolates %>% filter(if_any(carbapenems(), ~.x == "R")) # dplyr (formal)
# filter rows for resistance in all carbapenems
example_isolates[all(carbapenems() == "R"), ] # base R
example_isolates[carbapenems() == "R", ]
example_isolates %>% filter(all(carbapenems() == "R")) # dplyr
example_isolates %>% filter(carbapenems() == "R")as.rsi())custom_eucast_rules() that brings support for custom AMR rules in eucast_rules()
italicise_taxonomy() to make taxonomic names within a string italic, with support for markdown and ANSIfirst_isolate() function gained the argument method that has to be “phenotype-based”, “episode-based”, “patient-based”, or “isolate-based”. The old behaviour is equal to “episode-based”. The new default is “phenotype-based” if antimicrobial test results are available, and “episode-based” otherwise. This new default will yield slightly more isolates for selection (which is a good thing).key_antibiotics() and key_antibiotics_equal() are now deprecated in favour of the key_antimicrobials() and antimicrobials_equal() functions. Also, the new all_antimicrobials() function works like the old key_antibiotics() function, but includes any column with antimicrobial test results. Using key_antimicrobials() still only selects six preferred antibiotics for Gram-negatives, six for Gram-positives, and six universal antibiotics. It has a new antifungal argument to set antifungal agents (antimycotics).type == "points" in the first_isolate() function for phenotype-based selection will now consider all antimicrobial drugs in the data set, using the new all_antimicrobials()
first_isolate() function can now take a vector of values for col_keyantibiotics and can have an episode length of Inf
filter_first_isolate() renders the filter_first_weighted_isolate() function redundant. For this reason, filter_first_weighted_isolate() is now deprecated.first_isolate() and key_antimicrobials() functions has been completely rewritten.betalactams() as additional antbiotic column selector and function filter_betalactams() as additional antbiotic column filter. The group of betalactams consists of all carbapenems, cephalosporins and penicillins.ggplot() method for resistance_predict()

tinytest package, instead of the testthat package. The testthat package unfortunately requires tons of dependencies that are also heavy and only usable for recent R versions, disallowing developers to test a package under any R 3.* version. On the contrary, the tinytest package is very lightweight and dependency-free.Support for EUCAST Clinical Breakpoints v11.0 (2021), effective in the eucast_rules() function and in as.rsi() to interpret MIC and disk diffusion values. This is now the default guideline in this package.
eucast_dosage() to get a data.frame with advised dosages of a certain bug-drug combination, which is based on the new dosage data setdosage to fuel the new eucast_dosage() function and to make this data available in a structured wayexample_isolates now reflects the latest EUCAST rulesAdded argument only_rsi_columns for some functions, which defaults to FALSE, to indicate if the functions must only be applied to columns that are of class <rsi> (i.e., transformed with as.rsi()). This increases speed since automatic determination of antibiotic columns is not needed anymore. Affected functions are:
ab_class() and its wrappers, such as aminoglycosides(), carbapenems(), penicillins())filter_ab_class() and its wrappers, such as filter_aminoglycosides(), filter_carbapenems(), filter_penicillins())eucast_rules()mdro() (including wrappers such as brmo(), mrgn() and eucast_exceptional_phenotypes())guess_ab_col()Functions oxazolidinones() (an antibiotic selector function) and filter_oxazolidinones() (an antibiotic filter function) to select/filter on e.g. linezolid and tedizolid
Support for custom MDRO guidelines, using the new custom_mdro_guideline() function, please see mdro() for additional info
ggplot() generics for classes <mic> and <disk>
Function mo_is_yeast(), which determines whether a microorganism is a member of the taxonomic class Saccharomycetes or the taxonomic order Saccharomycetales:
mo_kingdom(c("Aspergillus", "Candida"))
#> [1] "Fungi" "Fungi"
mo_is_yeast(c("Aspergillus", "Candida"))
#> [1] FALSE TRUE
# usage for filtering data:
example_isolates[which(mo_is_yeast()), ] # base R
example_isolates %>% filter(mo_is_yeast()) # dplyrThe mo_type() function has also been updated to reflect this change:
Added Pretomanid (PMD, J04AK08) to the antibiotics data set
MIC values (see as.mic()) can now be used in any mathematical processing, such as usage inside functions min(), max(), range(), and with binary operators (+, -, etc.). This allows for easy distribution analysis and fast filtering on MIC values:
x <- random_mic(10)
x
#> Class <mic>
#> [1] 128 0.5 2 0.125 64 0.25 >=256 8 16 4
x[x > 4]
#> Class <mic>
#> [1] 128 64 >=256 8 16
range(x)
#> [1] 0.125 256.000
range(log2(x))

This drastically improves speed, also for a lot of other functions that rely on automatic determination of antibiotic columns.get_episode() and is_new_episode() now support less than a day as value for argument episode_days (e.g., to include one patient/test per hour)ampc_cephalosporin_resistance in eucast_rules() now also applies to value “I” (not only “S”)print() and summary() on a Principal Components Analysis object (pca()) now print additional group info if the original data was grouped using dplyr::group_by()
guess_ab_col(). As this also internally improves the reliability of first_isolate() and mdro(), this might have a slight impact on the results of those functions.mo_name() when used in other languages than Englishlike() function (and its fast alias %like%) now always use Perl compatibility, improving speed for many functions in this package (e.g., as.mo() is now up to 4 times faster)random_disk() and random_mic() now have an expanded range in their randomisationmo_genus("GISA") will return "Staphylococcus"

The get_episode() function returns the index number of the episode per group, while the is_new_episode() function returns values TRUE/FALSE to indicate whether an item in a vector is the start of a new episode. They also support dplyrs grouping (i.e. using group_by()):
Functions mo_is_gram_negative() and mo_is_gram_positive() as wrappers around mo_gramstain(). They always return TRUE or FALSE (except when the input is NA or the MO code is UNKNOWN), thus always return FALSE for species outside the taxonomic kingdom of Bacteria.
Function mo_is_intrinsic_resistant() to test for intrinsic resistance, based on EUCAST Intrinsic Resistance and Unusual Phenotypes v3.2 from 2020.
Functions random_mic(), random_disk() and random_rsi() for random value generation. The functions random_mic() and random_disk() take microorganism names and antibiotic names as input to make generation more realistic.
New argument ampc_cephalosporin_resistance in eucast_rules() to correct for AmpC de-repressed cephalosporin-resistant mutants
Interpretation of antimicrobial resistance - as.rsi():
as.rsi() can now be set by the user, using the reference_data argument. This allows for using own interpretation guidelines. The user-set data must have the same structure as rsi_translation.as.rsi() on a data.frameas.rsi() on a data.frame in older R versionsas.rsi() on a data.frame will not print a message anymore if the values are already clean R/SI valuesas.rsi() on MICs or disk diffusion while there is intrinsic antimicrobial resistance, a warning will be thrown to remind about thisas.rsi() on a data.frame that only contains one column for antibiotic interpretationsSome functions are now context-aware when used inside dplyr verbs, such as filter(), mutate() and summarise(). This means that then the data argument does not need to be set anymore. This is the case for the new functions:
… and for the existing functions:
first_isolate(),key_antibiotics(),mdro(),brmo(),mrgn(),mdr_tb(),mdr_cmi2012(),eucast_exceptional_phenotypes()
# to select first isolates that are Gram-negative
# and view results of cephalosporins and aminoglycosides:
library(dplyr)
example_isolates %>%
filter(first_isolate(), mo_is_gram_negative()) %>%
select(mo, cephalosporins(), aminoglycosides()) %>%
as_tibble()For antibiotic selection functions (such as cephalosporins(), aminoglycosides()) to select columns based on a certain antibiotic group, the dependency on the tidyselect package was removed, meaning that they can now also be used without the need to have this package installed and now also work in base R function calls (they rely on R 3.2 or later):
# above example in base R:
example_isolates[which(first_isolate() & mo_is_gram_negative()),
c("mo", cephalosporins(), aminoglycosides())]For all function arguments in the code, it is now defined what the exact type of user input should be (inspired by the typed package). If the user input for a certain function does not meet the requirements for a specific argument (such as the class or length), an informative error will be thrown. This makes the package more robust and the use of it more reproducible and reliable. In total, more than 420 arguments were defined.
Fix for set_mo_source(), that previously would not remember the file location of the original file
Deprecated function p_symbol() that not really fits the scope of this package. It will be removed in a future version. See here for the source code to preserve it.
Updated coagulase-negative staphylococci determination with Becker et al. 2020 (PMID 32056452), meaning that the species S. argensis, S. caeli, S. debuckii, S. edaphicus and S. pseudoxylosus are now all considered CoNS
Fix for using argument reference_df in as.mo() and mo_*() functions that contain old microbial codes (from previous package versions)
Fixed a bug where mo_uncertainties() would not return the results based on the MO matching score
Fixed a bug where as.mo() would not return results for known laboratory codes for microorganisms
Fixed a bug where as.ab() would sometimes fail
Better tibble printing for MIC values
Fix for plotting MIC values with plot()
Added plot() generic to class <disk>
LA-MRSA and CA-MRSA are now recognised as an abbreviation for Staphylococcus aureus, meaning that e.g. mo_genus("LA-MRSA") will return "Staphylococcus" and mo_is_gram_positive("LA-MRSA") will return TRUE.
Fix for printing class NA
Fix for mo_shortname() when the input contains NA
If as.mo() takes more than 30 seconds, some suggestions will be done to improve speed
options() were all removed in favour of a new internal environment pkg_env
sapply() calls with vapply())Support for ‘EUCAST Expert Rules’ / ‘EUCAST Intrinsic Resistance and Unusual Phenotypes’ version 3.2 of May 2020. With this addition to the previously implemented version 3.1 of 2016, the eucast_rules() function can now correct for more than 180 different antibiotics and the mdro() function can determine multidrug resistance based on more than 150 different antibiotics. All previously implemented versions of the EUCAST rules are now maintained and kept available in this package. The eucast_rules() function consequently gained the arguments version_breakpoints (at the moment defaults to v10.0, 2020) and version_expertrules (at the moment defaults to v3.2, 2020). The example_isolates data set now also reflects the change from v3.1 to v3.2. The mdro() function now accepts guideline == "EUCAST3.1" and guideline == "EUCAST3.2".
A new vignette and website page with info about all our public and freely available data sets, that can be downloaded as flat files or in formats for use in R, SPSS, SAS, Stata and Excel: https://msberends.github.io/AMR/articles/datasets.html
Data set intrinsic_resistant. This data set contains all bug-drug combinations where the ‘bug’ is intrinsic resistant to the ‘drug’ according to the latest EUCAST insights. It contains just two columns: microorganism and antibiotic.
Curious about which enterococci are actually intrinsic resistant to vancomycin?
Support for veterinary ATC codes
Support for skimming classes <rsi>, <mic>, <disk> and <mo> with the skimr package
Although advertised that this package should work under R 3.0.0, we still had a dependency on R 3.6.0. This is fixed, meaning that our package should now work under R 3.0.0.
Improvements for as.rsi():
Support for using dplyr’s across() to interpret MIC values or disk zone diameters, which also automatically determines the column with microorganism names or codes.
Cleaning columns in a data.frame now allows you to specify those columns with tidy selection, e.g. as.rsi(df, col1:col9)
Big speed improvement for interpreting MIC values and disk zone diameters. When interpreting 5,000 MIC values of two antibiotics (10,000 values in total), our benchmarks showed a total run time going from 80.7-85.1 seconds to 1.8-2.0 seconds.
Added argument ‘add_intrinsic_resistance’ (defaults to FALSE), that considers intrinsic resistance according to EUCAST
Fixed a bug where in EUCAST rules the breakpoint for R would be interpreted as “>=” while this should have been “<”
Added intelligent data cleaning to as.disk(), so numbers can also be extracted from text and decimal numbers will always be rounded up:
Improvements for as.mo():
mo_matching_score(). Any user input value that could mean more than one taxonomic entry is now considered ‘uncertain’. Instead of a warning, a message will be thrown and the accompanying mo_uncertainties() has been changed completely; it now prints all possible candidates with their matching score.mo_* functions like mo_name() on microoganism IDs.ignore_pattern to as.mo() which can also be given to mo_* functions like mo_name(), to exclude known non-relevant input from analysing. This can also be set with the option AMR_ignore_pattern.get_locale() now uses at default Sys.getenv("LANG") or, if LANG is not set, Sys.getlocale(). This can be overwritten by setting the option AMR_locale.
Big speed improvement for eucast_rules()
Overall speed improvement by tweaking joining functions
Function mo_shortname() now returns the genus for input where the species is unknown
BORSA is now recognised as an abbreviation for Staphylococcus aureus, meaning that e.g. mo_genus("BORSA") will return “Staphylococcus”
Added a feature from AMR 1.1.0 and earlier again, but now without other package dependencies: tibble printing support for classes <rsi>, <mic>, <disk>, <ab> and <mo>. When using tibbles containing antimicrobial columns (class <rsi>), “S” will print in green, “I” will print in yellow and “R” will print in red. Microbial IDs (class <mo>) will emphasise on the genus and species, not on the kingdom.
Names of antiviral agents in data set antivirals now have a starting capital letter, like it is the case in the antibiotics data set
Updated the documentation of the WHONET data set to clarify that all patient names are fictitious
Small as.ab() algorithm improvements
Fix for combining MIC values with raw numbers, i.e. c(as.mic(2), 2) previously failed but now returns a valid MIC class
ggplot_rsi() and geom_rsi() gained arguments minimum and language, to influence the internal use of rsi_df()
Changes in the antibiotics data set:
PEN)PNV) was removed, since its actual entry ‘Phenoxymethylpenicillin’ (code PHN) already existedantibiotics$group) of ‘Linezolid’ (LNZ), ‘Cycloserine’ (CYC), ‘Tedizolid’ (TZD) and ‘Thiacetazone’ (THA) is now “Oxazolidinones” instead of “Other antibacterials”Added support for using unique() on classes <rsi>, <mic>, <disk>, <ab> and <mo>
Added argument excess to the kurtosis() function (defaults to FALSE), to return the excess kurtosis, defined as the kurtosis minus three.
portion_R(), portion_S() and portion_I() that were deprecated since version 0.9.0 (November 2019) and were replaced with proportion_R(), proportion_S() and proportion_I()
base packageSuggests field of the DESCRIPTION fileFunction ab_from_text() to retrieve antimicrobial drug names, doses and forms of administration from clinical texts in e.g. health care records, which also corrects for misspelling since it uses as.ab() internally
Tidyverse selection helpers for antibiotic classes, that help to select the columns of antibiotics that are of a specific antibiotic class, without the need to define the columns or antibiotic abbreviations. They can be used in any function that allows selection helpers, like dplyr::select() and tidyr::pivot_longer():
library(dplyr)
# Columns 'IPM' and 'MEM' are in the example_isolates data set
example_isolates %>%
select(carbapenems())
#> Selecting carbapenems: `IPM` (imipenem), `MEM` (meropenem)Added mo_domain() as an alias to mo_kingdom()
Added function filter_penicillins() to filter isolates on a specific result in any column with a name in the antimicrobial ‘penicillins’ class (more specific: ATC subgroup Beta-lactam antibacterials, penicillins)
Added official antimicrobial names to all filter_ab_class() functions, such as filter_aminoglycosides()
Added antibiotics code “FOX1” for cefoxitin screening (abbreviation “cfsc”) to the antibiotics data set
Added Monuril as trade name for fosfomycin
Added argument conserve_capped_values to as.rsi() for interpreting MIC values - it makes sure that values starting with “<” (but not “<=”) will always return “S” and values starting with “>” (but not “>=”) will always return “R”. The default behaviour of as.rsi() has not changed, so you need to specifically do as.rsi(..., conserve_capped_values = TRUE).
Big speed improvement for using any function on microorganism codes from earlier package versions (prior to AMR v1.2.0), such as as.mo(), mo_name(), first_isolate(), eucast_rules(), mdro(), etc.
As a consequence, very old microbial codes (from AMR v0.5.0 and lower) are not supported anymore. Use as.mo() on your microorganism names or codes to transform them to current abbreviations used in this package.
Improvements for susceptibility() and resistance() and all count_*(), proportion_*() functions:
dplyr::all_of()) now works againImprovements for as.ab():
as.ab(), making many more input errors translatable, such as digitalised health care records, using too few or too many vowels or consonants and many moreas.ab() would return an error on invalid input valuesas.ab() function will now throw a note if more than 1 antimicrobial drug could be retrieved from a single input value.Fixed a bug where eucast_rules() would not work on a tibble when the tibble or dplyr package was loaded
Fixed a bug for CLSI 2019 guidelines (using as.rsi()), that also included results for animals. It now only contains interpretation guidelines for humans.
All *_join_microorganisms() functions and bug_drug_combinations() now return the original data class (e.g. tibbles and data.tables)
For functions rsi_df(), proportion_df() and count_df():
count_df()) when all antibiotics in the data set have only NAsImproved auto-determination for columns of types <mo> and <Date>
Fixed a bug in bug_drug_combinations() for when only one antibiotic was in the input data
Changed the summary for class <rsi>, to highlight the %SI vs. %R
Improved error handling, giving more useful info when functions return an error
Any progress bar will now only show in interactive mode (i.e. not in R Markdown)
Speed improvement for mdro() and filter_ab_class()
New option arrows_textangled for ggplot_pca() to indicate whether the text at the end of the arrows should be angled (defaults to TRUE, as it was in previous versions)
Added parenteral DDD to benzylpenicillin
Fixed a bug where as.mic() could not handle dots without a leading zero (like "<=.25)
Removed code dependency on all other R packages, making this package fully independent of the development process of others. This is a major code change, but will probably not be noticeable by most users.
Making this package independent of especially the tidyverse (e.g. packages dplyr and tidyr) tremendously increases sustainability on the long term, since tidyverse functions change quite often. Good for users, but hard for package maintainers. Most of our functions are replaced with versions that only rely on base R, which keeps this package fully functional for many years to come, without requiring a lot of maintenance to keep up with other packages anymore. Another upside it that this package can now be used with all versions of R since R-3.0.0 (April 2013). Our package is being used in settings where the resources are very limited. Fewer dependencies on newer software is helpful for such settings.
Negative effects of this change are:
freq() that was borrowed from the cleaner package was removed. Use cleaner::freq(), or run library("cleaner") before you use freq().mo or rsi in a tibble will no longer be in colour and printing rsi in a tibble will show the class <ord>, not <rsi> anymore. This is purely a visual effect.mo_* family (like mo_name() and mo_gramstain()) are noticeably slower when running on hundreds of thousands of rows.mo and ab now both also inherit class character, to support any data transformation. This change invalidates code that checks for class length == 1.first_isolate()), since some bacterial names might be renamed to other genera or other (sub)species. This is expected behaviour.eucast_rules() function no longer applies “other” rules at default that are made available by this package (like setting ampicillin = R when ampicillin + enzyme inhibitor = R). The default input value for rules is now c("breakpoints", "expert") instead of "all", but this can be changed by the user. To return to the old behaviour, set options(AMR.eucast_rules = "all").antibiotics data set these two rules:
eucast_rules()
ab_url() to return the direct URL of an antimicrobial agent from the official WHO websiteas.ab(), so that e.g. as.ab("ampi sul") and ab_name("ampi sul") workab_atc() and ab_group() now return NA if no antimicrobial agent could be foundset_mo_source() to make sure that column mo will always be the second columnpca() functionggplot_pca() functionas.mo() (and consequently all mo_* functions, that use as.mo() internally):

antibiotics data setas.rsi() for years 2010-2019 (thanks to Anthony Underwood)Fixed important floating point error for some MIC comparisons in EUCAST 2020 guideline
Interpretation from MIC values (and disk zones) to R/SI can now be used with mutate_at() of the dplyr package:
Added antibiotic abbreviations for a laboratory manufacturer (GLIMS) for cefuroxime, cefotaxime, ceftazidime, cefepime, cefoxitin and trimethoprim/sulfamethoxazole
Added uti (as abbreviation of urinary tract infections) as argument to as.rsi(), so interpretation of MIC values and disk zones can be made dependent on isolates specifically from UTIs
Info printing in functions eucast_rules(), first_isolate(), mdro() and resistance_predict() will now at default only print when R is in an interactive mode (i.e. not in RMarkdown)
This software is now out of beta and considered stable. Nonetheless, this package will be developed continually.
as.rsi() and inferred resistance and susceptibility using eucast_rules().Support for LOINC codes in the antibiotics data set. Use ab_loinc() to retrieve LOINC codes, or use a LOINC code for input in any ab_* function:
Support for SNOMED CT codes in the microorganisms data set. Use mo_snomed() to retrieve SNOMED codes, or use a SNOMED code for input in any mo_* function:
mo_snomed("S. aureus")

Please note that the combination rifampicin/isoniazid has no DDDs defined, so e.g. ab_ddd("Rimactazid") will now return NA.SMX) to trimethoprim/sulfamethoxazole (SXT)microorganisms data set, which means that the new order Enterobacterales now consists of a part of the existing family Enterobacteriaceae, but that this family has been split into other families as well (like Morganellaceae and Yersiniaceae). Although published in 2016, this information is not yet in the Catalogue of Life version of 2019. All MDRO determinations with mdro() will now use the Enterobacterales order for all guidelines before 2016 that were dependent on the Enterobacteriaceae family.
Functions susceptibility() and resistance() as aliases of proportion_SI() and proportion_R(), respectively. These functions were added to make it more clear that “I” should be considered susceptible and not resistant.
Support for a new MDRO guideline: Magiorakos AP, Srinivasan A et al. “Multidrug-resistant, extensively drug-resistant and pandrug-resistant bacteria: an international expert proposal for interim standard definitions for acquired resistance.” Clinical Microbiology and Infection (2012).
mdro() functionmdro(...., verbose = TRUE)) returns an informative data set where the reason for MDRO determination is given for every isolate, and an list of the resistant antimicrobial agentsData set antivirals, containing all entries from the ATC J05 group with their DDDs for oral and parenteral treatment
as.mo():
Now allows “ou” where “au” should have been used and vice versa
More intelligent way of coping with some consonants like “l” and “r”
Added a score (a certainty percentage) to mo_uncertainties(), that is calculated using the Levenshtein distance:
as.mo(c("Stafylococcus aureus",
"staphylokok aureuz"))
#> Warning:
#> Results of two values were guessed with uncertainty. Use mo_uncertainties() to review them.
#> Class 'mo'

clean to cleaner, as this package was renamed accordingly upon CRAN requestDetermination of first isolates now excludes all ‘unknown’ microorganisms at default, i.e. microbial code "UNKNOWN". They can be included with the new argument include_unknown:
first_isolate(..., include_unknown = TRUE)For WHONET users, this means that all records/isolates with organism code "con" (contamination) will be excluded at default, since as.mo("con") = "UNKNOWN". The function always shows a note with the number of ‘unknown’ microorganisms that were included or excluded.
For code consistency, classes ab and mo will now be preserved in any subsetting or assignment. For the sake of data integrity, this means that invalid assignments will now result in NA:
# how it works in base R:
x <- factor("A")
x[1] <- "B"
#> Warning message:
#> invalid factor level, NA generated
# how it now works similarly for classes 'mo' and 'ab':
x <- as.mo("E. coli")
x[1] <- "testvalue"
#> Warning message:
#> invalid microorganism code, NA generatedThis is important, because a value like "testvalue" could never be understood by e.g. mo_name(), although the class would suggest a valid microbial code.
Function freq() has moved to a new package, clean (CRAN link), since creating frequency tables actually does not fit the scope of this package. The freq() function still works, since it is re-exported from the clean package (which will be installed automatically upon updating this AMR package).
Renamed data set septic_patients to example_isolates
Function bug_drug_combinations() to quickly get a data.frame with the results of all bug-drug combinations in a data set. The column containing microorganism codes is guessed automatically and its input is transformed with mo_shortname() at default:
x <- bug_drug_combinations(example_isolates)
#> NOTE: Using column `mo` as input for `col_mo`.
x[1:4, ]
#> mo ab S I R total
#> 1 A. baumannii AMC 0 0 3 3
#> 2 A. baumannii AMK 0 0 0 0
#> 3 A. baumannii AMP 0 0 3 3
#> 4 A. baumannii AMX 0 0 3 3
#> NOTE: Use 'format()' on this result to get a publicable/printable format.
# change the transformation with the FUN argument to anything you like:
x <- bug_drug_combinations(example_isolates, FUN = mo_gramstain)
#> NOTE: Using column `mo` as input for `col_mo`.
x[1:4, ]
#> mo ab S I R total
#> 1 Gram-negative AMC 469 89 174 732
#> 2 Gram-negative AMK 251 0 2 253
#> 3 Gram-negative AMP 227 0 405 632
#> 4 Gram-negative AMX 227 0 405 632
#> NOTE: Use 'format()' on this result to get a publicable/printable format.You can format this to a printable format, ready for reporting or exporting to e.g. Excel with the base R format() function:
format(x, combine_IR = FALSE)Additional way to calculate co-resistance, i.e. when using multiple antimicrobials as input for portion_* functions or count_* functions. This can be used to determine the empiric susceptibility of a combination therapy. A new argument only_all_tested (which defaults to FALSE) replaces the old also_single_tested and can be used to select one of the two methods to count isolates and calculate portions. The difference can be seen in this example table (which is also on the portion and count help pages), where the %SI is being determined:
# --------------------------------------------------------------------
# only_all_tested = FALSE only_all_tested = TRUE
# ----------------------- -----------------------
# Drug A Drug B include as include as include as include as
# numerator denominator numerator denominator
# -------- -------- ---------- ----------- ---------- -----------
# S or I S or I X X X X
# R S or I X X X X
# <NA> S or I X X - -
# S or I R X X X X
# R R - X - X
# <NA> R - - - -
# S or I <NA> X X - -
# R <NA> - - - -
# <NA> <NA> - - - -
# --------------------------------------------------------------------Since this is a major change, usage of the old also_single_tested will throw an informative error that it has been replaced by only_all_tested.
tibble printing support for classes rsi, mic, disk, ab mo. When using tibbles containing antimicrobial columns, values S will print in green, values I will print in yellow and values R will print in red. Microbial IDs (class mo) will emphasise on the genus and species, not on the kingdom.
as.mo() (of which some led to additions to the microorganisms data set). Many thanks to all contributors that helped improving the algorithms.
B_ENTRC_FAE could have been both E. faecalis and E. faecium. Its new code is B_ENTRC_FCLS and E. faecium has become B_ENTRC_FACM. Also, the Latin character ae is now preserved at the start of each genus and species abbreviation. For example, the old code for Aerococcus urinae was B_ARCCC_NAE. This is now B_AERCC_URIN. IMPORTANT: Old microorganism IDs are still supported, but support will be dropped in a future version. Use as.mo() on your old codes to transform them to the new format. Using functions from the mo_* family (like mo_name() and mo_gramstain()) on old codes, will throw a warning.as.ab(), including bidirectional language supportmdro() function, to determine multi-drug resistant organismseucast_rules():

as.mic())Function rsi_df() to transform a data.frame to a data set containing only the microbial interpretation (S, I, R), the antibiotic, the percentage of S/I/R and the number of available isolates. This is a convenient combination of the existing functions count_df() and portion_df() to immediately show resistance percentages and number of available isolates:
Support for all scientifically published pathotypes of E. coli to date (that we could find). Supported are:
All these lead to the microbial ID of E. coli:

New website!
We’ve got a new website: https://msberends.gitlab.io/AMR (built with the great pkgdown)
BREAKING: removed deprecated functions, arguments and references to ‘bactid’. Use as.mo() to identify an MO code.
Catalogue of Life as a new taxonomic source for data about microorganisms, which also contains all ITIS data we used previously. The microorganisms data set now contains:
All ~55,000 (sub)species from the kingdoms of Archaea, Bacteria and Protozoa
All ~3,000 (sub)species from these orders of the kingdom of Fungi: Eurotiales, Onygenales, Pneumocystales, Saccharomycetales and Schizosaccharomycetales (covering at least like all species of Aspergillus, Candida, Pneumocystis, Saccharomyces and Trichophyton)
All ~2,000 (sub)species from ~100 other relevant genera, from the kingdoms of Animalia and Plantae (like Strongyloides and Taenia)
All ~15,000 previously accepted names of included (sub)species that have been taxonomically renamed
The responsible author(s) and year of scientific publication
This data is updated annually - check the included version with the new function catalogue_of_life_version().
Due to this change, some mo codes changed (e.g. Streptococcus changed from B_STRPTC to B_STRPT). A translation table is used internally to support older microorganism IDs, so users will not notice this difference.
New function mo_rank() for the taxonomic rank (genus, species, infraspecies, etc.)
New function mo_url() to get the direct URL of a species from the Catalogue of Life
Support for data from WHONET and EARS-Net (European Antimicrobial Resistance Surveillance Network):
first_isolate() and eucast_rules(), all arguments will be filled in automatically.antibiotics data set now contains a column ears_net.as.mo() now knows all WHONET species abbreviations too, because almost 2,000 microbial abbreviations were added to the microorganisms.codes data set.New filters for antimicrobial classes. Use these functions to filter isolates on results in one of more antibiotics from a specific class:
filter_aminoglycosides()
filter_carbapenems()
filter_cephalosporins()
filter_1st_cephalosporins()
filter_2nd_cephalosporins()
filter_3rd_cephalosporins()
filter_4th_cephalosporins()
filter_fluoroquinolones()
filter_glycopeptides()
filter_macrolides()
filter_tetracyclines()The antibiotics data set will be searched, after which the input data will be checked for column names with a value in any abbreviations, codes or official names found in the antibiotics data set. For example:
All ab_* functions are deprecated and replaced by atc_* functions:
ab_property -> atc_property()
ab_name -> atc_name()
ab_official -> atc_official()
ab_trivial_nl -> atc_trivial_nl()
ab_certe -> atc_certe()
ab_umcg -> atc_umcg()
ab_tradenames -> atc_tradenames()These functions use as.atc() internally. The old atc_property has been renamed atc_online_property(). This is done for two reasons: firstly, not all ATC codes are of antibiotics (ab) but can also be of antivirals or antifungals. Secondly, the input must have class atc or must be coerable to this class. Properties of these classes should start with the same class name, analogous to as.mo() and e.g. mo_genus.
New functions set_mo_source() and get_mo_source() to use your own predefined MO codes as input for as.mo() and consequently all mo_* functions
Support for the upcoming dplyr version 0.8.0
New function guess_ab_col() to find an antibiotic column in a table
New function mo_failures() to review values that could not be coerced to a valid MO code, using as.mo(). This latter function will now only show a maximum of 10 uncoerced values and will refer to mo_failures().
New function mo_uncertainties() to review values that could be coerced to a valid MO code using as.mo(), but with uncertainty.
New function mo_renamed() to get a list of all returned values from as.mo() that have had taxonomic renaming
New function age() to calculate the (patients) age in years
New function age_groups() to split ages into custom or predefined groups (like children or elderly). This allows for easier demographic AMR data analysis per age group.
New function ggplot_rsi_predict() as well as the base R plot() function can now be used for resistance prediction calculated with resistance_predict():
x <- resistance_predict(septic_patients, col_ab = "amox")
plot(x)
ggplot_rsi_predict(x)Functions filter_first_isolate() and filter_first_weighted_isolate() to shorten and fasten filtering on data sets with antimicrobial results, e.g.:
septic_patients %>% filter_first_isolate(...)
# or
filter_first_isolate(septic_patients, ...)is equal to:
New function availability() to check the number of available (non-empty) results in a data.frame
New vignettes about how to conduct AMR analysis, predict antimicrobial resistance, use the G-test and more. These are also available (and even easier readable) on our website: https://msberends.gitlab.io/AMR.
eucast_rules():

The old functions are deprecated and will be removed in a future version.guess_mo() is now deprecated in favour of as.mo() and will be removed in future versionsguess_atc() is now deprecated in favour of as.atc() and will be removed in future versionsas.mo():
Now handles incorrect spelling, like i instead of y and f instead of ph:
# mo_fullname() uses as.mo() internally
mo_fullname("Sthafilokockus aaureuz")
#> [1] "Staphylococcus aureus"
mo_fullname("S. klossi")
#> [1] "Staphylococcus kloosii"Uncertainty of the algorithm is now divided into four levels, 0 to 3, where the default allow_uncertain = TRUE is equal to uncertainty level 2. Run ?as.mo for more info about these levels.
# equal:
as.mo(..., allow_uncertain = TRUE)
as.mo(..., allow_uncertain = 2)
# also equal:
as.mo(..., allow_uncertain = FALSE)
as.mo(..., allow_uncertain = 0)Using as.mo(..., allow_uncertain = 3) could lead to very unreliable results.
Implemented the latest publication of Becker et al. (2019), for categorising coagulase-negative Staphylococci
All microbial IDs that found are now saved to a local file ~/.Rhistory_mo. Use the new function clean_mo_history() to delete this file, which resets the algorithms.
Incoercible results will now be considered ‘unknown’, MO code UNKNOWN. On foreign systems, properties of these will be translated to all languages already previously supported: German, Dutch, French, Italian, Spanish and Portuguese.

Tremendous speed improvement for as.mo (and subsequently all mo_* functions), as empty values wil be ignored a priori
Fewer than 3 characters as input for as.mo will return NA
Function as.mo (and all mo_* wrappers) now supports genus abbreviations with “species” attached
as.mo("E. species") # B_ESCHR

as.mo("S. spp") # B_STPHY
mo_fullname("S. species") # "Staphylococcus species"Added argument combine_IR (TRUE/FALSE) to functions portion_df and count_df, to indicate that all values of I and R must be merged into one, so the output only consists of S vs. IR (susceptible vs. non-susceptible)
Fix for portion_*(..., as_percent = TRUE) when minimal number of isolates would not be met
Added argument also_single_tested for portion_* and count_* functions to also include cases where not all antibiotics were tested but at least one of the tested antibiotics includes the target antimicribial interpretation, see ?portion
Using portion_* functions now throws a warning when total available isolate is below argument minimum
Functions as.mo, as.rsi, as.mic, as.atc and freq will not set package name as attribute anymore
Frequency tables - freq():
Support for grouping variables, test with:
Support for (un)selecting columns:

The data set microorganisms now contains all microbial taxonomic data from ITIS (kingdoms Bacteria, Fungi and Protozoa), the Integrated Taxonomy Information System, available via https://itis.gov. The data set now contains more than 18,000 microorganisms with all known bacteria, fungi and protozoa according ITIS with genus, species, subspecies, family, order, class, phylum and subkingdom. The new data set microorganisms.old contains all previously known taxonomic names from those kingdoms.
New functions based on the existing function mo_property:
mo_phylum, mo_class, mo_order, mo_family, mo_genus, mo_species, mo_subspecies
mo_fullname, mo_shortname
mo_type, mo_gramstain
mo_ref
They also come with support for German, Dutch, French, Italian, Spanish and Portuguese:
mo_gramstain("E. coli")
# [1] "Gram negative"
mo_gramstain("E. coli", language = "de") # German
# [1] "Gramnegativ"
mo_gramstain("E. coli", language = "es") # Spanish
# [1] "Gram negativo"
mo_fullname("S. group A", language = "pt") # Portuguese
# [1] "Streptococcus grupo A"Furthermore, former taxonomic names will give a note about the current taxonomic name:
mo_gramstain("Esc blattae")
# Note: 'Escherichia blattae' (Burgess et al., 1973) was renamed 'Shimwellia blattae' (Priest and Barker, 2010)
# [1] "Gram negative"Functions count_R, count_IR, count_I, count_SI and count_S to selectively count resistant or susceptible isolates
count_df (which works like portion_df) to get all counts of S, I and R of a data set with antibiotic columns, with support for grouped variablesFunction is.rsi.eligible to check for columns that have valid antimicrobial results, but do not have the rsi class yet. Transform the columns of your raw data with: data %>% mutate_if(is.rsi.eligible, as.rsi)
Functions as.mo and is.mo as replacements for as.bactid and is.bactid (since the microoganisms data set not only contains bacteria). These last two functions are deprecated and will be removed in a future release. The as.mo function determines microbial IDs using intelligent rules:
as.mo("E. coli")
# [1] B_ESCHR_COL
as.mo("MRSA")
# [1] B_STPHY_AUR
as.mo("S group A")
# [1] B_STRPTC_GRAAnd with great speed too - on a quite regular Linux server from 2007 it takes us less than 0.02 seconds to transform 25,000 items:
thousands_of_E_colis <- rep("E. coli", 25000)
microbenchmark::microbenchmark(as.mo(thousands_of_E_colis), unit = "s")
# Unit: seconds
# min median max neval
# 0.01817717 0.01843957 0.03878077 100Added argument reference_df for as.mo, so users can supply their own microbial IDs, name or codes as a reference table
Renamed all previous references to bactid to mo, like:
EUCAST_rules, first_isolate and key_antibiotics
microorganisms and septic_patients
Function labels_rsi_count to print datalabels on a RSI ggplot2 model
Functions as.atc and is.atc to transform/look up antibiotic ATC codes as defined by the WHO. The existing function guess_atc is now an alias of as.atc.
Function ab_property and its aliases: ab_name, ab_tradenames, ab_certe, ab_umcg and ab_trivial_nl
Introduction to AMR as a vignette
Removed clipboard functions as it violated the CRAN policy
Renamed septic_patients$sex to septic_patients$gender
Added three antimicrobial agents to the antibiotics data set: Terbinafine (D01BA02), Rifaximin (A07AA11) and Isoconazole (D01AC05)
Added 163 trade names to the antibiotics data set, it now contains 298 different trade names in total, e.g.:
For first_isolate, rows will be ignored when there’s no species available
Function ratio is now deprecated and will be removed in a future release, as it is not really the scope of this package
Fix for as.mic for values ending in zeroes after a real number
Small fix where B. fragilis would not be found in the microorganisms.umcg data set
Added prevalence column to the microorganisms data set
Added arguments minimum and as_percent to portion_df
Support for quasiquotation in the functions series count_* and portions_*, and n_rsi. This allows to check for more than 2 vectors or columns.
Edited ggplot_rsi and geom_rsi so they can cope with count_df. The new fun argument has value portion_df at default, but can be set to count_df.
Fix for ggplot_rsi when the ggplot2 package was not loaded
Added datalabels function labels_rsi_count to ggplot_rsi
Added possibility to set any argument to geom_rsi (and ggplot_rsi) so you can set your own preferences
Fix for joins, where predefined suffices would not be honoured
Added argument quote to the freq function
Added generic function diff for frequency tables
Added longest en shortest character length in the frequency table (freq) header of class character
Support for types (classes) list and matrix for freq
For lists, subsetting is possible:
rsi_df was removed in favour of new functions portion_R, portion_IR, portion_I, portion_SI and portion_S to selectively calculate resistance or susceptibility. These functions are 20 to 30 times faster than the old rsi function. The old function still works, but is deprecated.
portion_df to get all portions of S, I and R of a data set with antibiotic columns, with support for grouped variablesggplot2
geom_rsi, facet_rsi, scale_y_percent, scale_rsi_colours and theme_rsi
ggplot_rsi to apply all above functions on a data set:
septic_patients %>% select(tobr, gent) %>% ggplot_rsi will show portions of S, I and R immediately in a pretty plot?ggplot_rsi
as.bactid and is.bactid to transform/ look up microbial ID’s.guess_bactid is now an alias of as.bactid
kurtosis and skewness that are lacking in base R - they are generic functions and have support for vectors, data.frames and matricesg.test to perform the X2 distributed G-test, which use is the same as chisq.test
ratio to transform a vector of values to a preset ratioratio(c(10, 500, 10), ratio = "1:2:1") would return 130, 260, 130%in% or %like% (and give them keyboard shortcuts), or to view the datasets that come with this packagep.symbol to transform p values to their related symbols: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1
clipboard_import and clipboard_export as helper functions to quickly copy and paste from/to software like Excel and SPSS. These functions use the clipr package, but are a little altered to also support headless Linux servers (so you can use it in RStudio Server)freq):
rsi (antimicrobial resistance) to use as inputtable to use as input: freq(table(x, y))
hist and plot to use a frequency table as input: hist(freq(df$age))
as.vector, as.data.frame, as_tibble and format
freq(mydata, mycolumn) is the same as mydata %>% freq(mycolumn)
top_freq function to return the top/below n items as vectoroptions(max.print.freq = n) where n is your preset valueresistance_predict and added more examplesseptic_patients data set to better reflect the realitymic and rsi classes now returns all values - use freq to check distributionskey_antibiotics function are now generic: 6 for broadspectrum ABs, 6 for Gram-positive specific and 6 for Gram-negative specific ABsabname function%like% now supports multiple patternsdata.frames with altered console printing to make it look like a frequency table. Because of this, the argument toConsole is not longer needed.freq where the class of an item would be lostseptic_patients dataset and the column bactid now has the new class "bactid"
microorganisms dataset (especially for Salmonella) and the column bactid now has the new class "bactid"
rsi and mic functions:
as.rsi("<=0.002; S") will return S
as.mic("<=0.002; S") will return <=0.002
as.mic("<= 0.002") now worksrsi and mic do not add the attribute package.version anymore"groups" option for atc_property(..., property). It will return a vector of the ATC hierarchy as defined by the WHO. The new function atc_groups is a convenient wrapper around this.atc_property as it requires the host set by url to be responsivefirst_isolate algorithm to exclude isolates where bacteria ID or genus is unavailable924b62) from the dplyr package v0.7.5 and aboveguess_bactid (now called as.bactid)
yourdata %>% select(genus, species) %>% as.bactid() now also worksn_rsi to count cases where antibiotic test results were available, to be used in conjunction with dplyr::summarise, see ?rsiguess_bactid to determine the ID of a microorganism based on genus/species or known abbreviations like MRSAguess_atc to determine the ATC of an antibiotic based on name, trade name, or known abbreviationsfreq to create frequency tables, with additional info in a headerMDRO to determine Multi Drug Resistant Organisms (MDRO) with support for country-specific guidelines.
