Function reference • AMR (for R)

Preparing data: microorganisms

These functions are meant to get taxonomically valid properties of microorganisms from any input. Use mo_source() to teach this package how to translate your own codes to valid microorganism codes.

as.mo() is.mo() mo_uncertainties() mo_renamed() mo_failures() mo_reset_session() mo_cleaning_regex(): Transform Input to a Microorganism Code

mo_name() mo_fullname() mo_shortname() mo_subspecies() mo_species() mo_genus() mo_family() mo_order() mo_class() mo_phylum() mo_kingdom() mo_domain() mo_type() mo_status() mo_gramstain() mo_is_gram_negative() mo_is_gram_positive() mo_is_yeast() mo_is_intrinsic_resistant() mo_snomed() mo_ref() mo_authors() mo_year() mo_lpsn() mo_gbif() mo_rank() mo_taxonomy() mo_synonyms() mo_current() mo_info() mo_url() mo_property(): Get Properties of a Microorganism

set_mo_source() get_mo_source(): User-Defined Reference Data Set for Microorganisms

Preparing data: antibiotics

Use these functions to get valid properties of antibiotics from any input or to clean your input. You can even retrieve drug names and doses from clinical text records, using ab_from_text().

as.ab() is.ab(): Transform Input to an Antibiotic ID

ab_name() ab_cid() ab_synonyms() ab_tradenames() ab_group() ab_atc() ab_atc_group1() ab_atc_group2() ab_loinc() ab_ddd() ab_ddd_units() ab_info() ab_url() ab_property() set_ab_names(): Get Properties of an Antibiotic

ab_from_text(): Retrieve Antimicrobial Drug Names and Doses from Clinical Text

atc_online_property() atc_online_groups() atc_online_ddd() atc_online_ddd_units(): Get ATC Properties from WHOCC Website

add_custom_antimicrobials() clear_custom_antimicrobials(): Add Custom Antimicrobials to This Package

Preparing data: antimicrobial resistance

With as.mic() and as.disk() you can transform your raw input to valid MIC or disk diffusion values. Use as.rsi() for cleaning raw data to let it only contain “R”, “I” and “S”, or to interpret MIC or disk diffusion values as R/SI based on the lastest EUCAST and CLSI guidelines. Afterwards, you can extend antibiotic interpretations by applying EUCAST rules with eucast_rules().

as.rsi() NA_rsi_ is.rsi() is.rsi.eligible() rsi_interpretation_history(): Interpret MIC and Disk Values, or Clean Raw R/SI Data

as.mic() NA_mic_ is.mic() droplevels(<mic>): Transform Input to Minimum Inhibitory Concentrations (MIC)

as.disk() NA_disk_ is.disk(): Transform Input to Disk Diffusion Diameters

eucast_rules() eucast_dosage(): Apply EUCAST Rules

custom_eucast_rules(): Define Custom EUCAST Rules

Analysing data: antimicrobial resistance

Use these function for the analysis part. You can use susceptibility() or resistance() on any antibiotic column. Be sure to first select the isolates that are appropiate for analysis, by using first_isolate() or is_new_episode(). You can also filter your data on certain resistance in certain antibiotic classes (carbapenems(), aminoglycosides()), or determine multi-drug resistant microorganisms (MDRO, mdro()).

resistance() susceptibility() rsi_confidence_interval() proportion_R() proportion_IR() proportion_I() proportion_SI() proportion_S() proportion_df() rsi_df(): Calculate Microbial Resistance

count_resistant() count_susceptible() count_R() count_IR() count_I() count_SI() count_S() count_all() n_rsi() count_df(): Count Available Isolates

get_episode() is_new_episode(): Determine (New) Episodes for Patients

first_isolate() filter_first_isolate(): Determine First Isolates

key_antimicrobials() all_antimicrobials() antimicrobials_equal(): (Key) Antimicrobials for First Weighted Isolates

mdro() custom_mdro_guideline() brmo() mrgn() mdr_tb() mdr_cmi2012() eucast_exceptional_phenotypes(): Determine Multidrug-Resistant Organisms (MDRO)

plot(<mic>) autoplot(<mic>) fortify(<mic>) plot(<disk>) autoplot(<disk>) fortify(<disk>) plot(<rsi>) autoplot(<rsi>) fortify(<rsi>): Plotting for Classes rsi, mic and disk

ggplot_rsi() geom_rsi() facet_rsi() scale_y_percent() scale_rsi_colours() theme_rsi() labels_rsi_count(): AMR Plots with ggplot2

bug_drug_combinations() format(<bug_drug_combinations>): Determine Bug-Drug Combinations

ab_class() ab_selector() aminoglycosides() aminopenicillins() antifungals() antimycobacterials() betalactams() carbapenems() cephalosporins() cephalosporins_1st() cephalosporins_2nd() cephalosporins_3rd() cephalosporins_4th() cephalosporins_5th() fluoroquinolones() glycopeptides() lincosamides() lipoglycopeptides() macrolides() oxazolidinones() penicillins() polymyxins() streptogramins() quinolones() tetracyclines() trimethoprims() ureidopenicillins() administrable_per_os() administrable_iv() not_intrinsic_resistant(): Antibiotic Selectors
