Get Properties of an Antibiotic

Use these functions to return a specific property of an antibiotic from the antibiotics data set. All input values will be evaluated internally with as.ab().

ab_name(x, language = get_locale(), tolower = FALSE, ...)

set_ab_names(
  data,
  property = "name",
  language = get_locale(),
  snake_case = property == "name"
)

ab_atc(x, ...)

ab_cid(x, ...)

ab_synonyms(x, ...)

ab_tradenames(x, ...)

ab_group(x, language = get_locale(), ...)

ab_atc_group1(x, language = get_locale(), ...)

ab_atc_group2(x, language = get_locale(), ...)

ab_loinc(x, ...)

ab_ddd(x, administration = "oral", ...)

ab_ddd_units(x, administration = "oral", ...)

ab_info(x, language = get_locale(), ...)

ab_url(x, open = FALSE, ...)

ab_property(x, property = "name", language = get_locale(), ...)

Arguments

x	any (vector of) text that can be coerced to a valid antibiotic code with `as.ab()`
language	language of the returned text, defaults to system language (see `get_locale()`) and can also be set with `getOption("AMR_locale")`. Use `language = NULL` or `language = ""` to prevent translation.
tolower	a logical to indicate whether the first character of every output should be transformed to a lower case character. This will lead to e.g. "polymyxin B" and not "polymyxin b".
...	other arguments passed on to `as.ab()`
data	a data.frame of which the columns need to be renamed
property	one of the column names of one of the antibiotics data set: `vector_or(colnames(antibiotics), sort = FALSE)`.
snake_case	a logical to indicate whether the names should be in so-called snake case: in lower case and all spaces/slashes replaced with an underscore (`_`)
administration	way of administration, either `"oral"` or `"iv"`
open	browse the URL using `utils::browseURL()`

Value

An integer in case of ab_cid()
A named list in case of ab_info() and multiple ab_atc()/ab_synonyms()/ab_tradenames()
A double in case of ab_ddd()
A data.frame in case of set_ab_names()
A character in all other cases

Details

All output will be translated where possible.

The function ab_url() will return the direct URL to the official WHO website. A warning will be returned if the required ATC code is not available.

The function set_ab_names() is a special column renaming function for data.frames. It renames columns names that resemble antimicrobial drugs. It always makes sure that the new column names are unique. If property = "atc" is set, preference is given to ATC codes from the J-group.

Stable Lifecycle

The lifecycle of this function is stable. In a stable function, major changes are unlikely. This means that the unlying code will generally evolve by adding new arguments; removing arguments or changing the meaning of existing arguments will be avoided.

If the unlying code needs breaking changes, they will occur gradually. For example, a argument will be deprecated and first continue to work, but will emit an message informing you of the change. Next, typically after at least one newly released version on CRAN, the message will be transformed to an error.

Reference Data Publicly Available

All reference data sets (about microorganisms, antibiotics, R/SI interpretation, EUCAST rules, etc.) in this AMR package are publicly and freely available. We continually export our data sets to formats for use in R, SPSS, SAS, Stata and Excel. We also supply flat files that are machine-readable and suitable for input in any software program, such as laboratory information systems.

Examples

# all properties:
ab_name("AMX")       # "Amoxicillin"
ab_atc("AMX")        # J01CA04 (ATC code from the WHO)
ab_cid("AMX")        # 33613 (Compound ID from PubChem)
ab_synonyms("AMX")   # a list with brand names of amoxicillin
ab_tradenames("AMX") # same
ab_group("AMX")      # "Beta-lactams/penicillins"
ab_atc_group1("AMX") # "Beta-lactam antibacterials, penicillins"
ab_atc_group2("AMX") # "Penicillins with extended spectrum"
ab_url("AMX")        # link to the official WHO page

# smart lowercase tranformation
ab_name(x = c("AMC", "PLB"))  # "Amoxicillin/clavulanic acid" "Polymyxin B"
ab_name(x = c("AMC", "PLB"),
        tolower = TRUE)       # "amoxicillin/clavulanic acid" "polymyxin B"

# defined daily doses (DDD)
ab_ddd("AMX", "oral")       #  1.5
ab_ddd_units("AMX", "oral") # "g"
ab_ddd("AMX", "iv")         #  3
ab_ddd_units("AMX", "iv")   # "g"

ab_info("AMX")       # all properties as a list

# all ab_* functions use as.ab() internally, so you can go from 'any' to 'any':
ab_atc("AMP")           # ATC code of AMP (ampicillin)
ab_group("J01CA01")     # Drug group of ampicillins ATC code
ab_loinc("ampicillin")  # LOINC codes of ampicillin
ab_name("21066-6")      # "Ampicillin" (using LOINC)
ab_name(6249)           # "Ampicillin" (using CID)
ab_name("J01CA01")      # "Ampicillin" (using ATC)

# spelling from different languages and dyslexia are no problem
ab_atc("ceftriaxon")
ab_atc("cephtriaxone")
ab_atc("cephthriaxone")
ab_atc("seephthriaaksone")

# use set_ab_names() for renaming columns
colnames(example_isolates)
colnames(set_ab_names(example_isolates))
# \donttest{
if (require("dplyr")) {
  example_isolates %>%
    set_ab_names()
