Function reference • AMR (for R)

Preparing data: microorganisms

These functions are meant to get taxonomically valid properties of microorganisms from any input, but also properties derived from taxonomy, such as the Gram stain (mo_gramstain()) , or mo_is_yeast(). Use mo_source() to teach this package how to translate your own codes to valid microorganisms, and use `add_custom_microorganisms() to add your own custom microorganisms to this package.

as.mo() is.mo() mo_uncertainties() mo_renamed() mo_failures() mo_reset_session() mo_cleaning_regex(): Transform Arbitrary Input to Valid Microbial Taxonomy

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_pathogenicity() mo_gramstain() mo_is_gram_negative() mo_is_gram_positive() mo_is_yeast() mo_is_intrinsic_resistant() mo_oxygen_tolerance() mo_is_anaerobic() 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

add_custom_microorganisms() clear_custom_microorganisms(): Add Custom Microorganisms

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

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.sir() for cleaning raw data to let it only contain “R”, “I” and “S”, or to interpret MIC or disk diffusion values as SIR based on the lastest EUCAST and CLSI guidelines. Afterwards, you can extend antibiotic interpretations by applying EUCAST rules with eucast_rules().

as.sir() NA_sir_ is.sir() is_sir_eligible() sir_interpretation_history(): Translate MIC and Disk Diffusion to SIR, or Clean Existing SIR 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. With antibiogram(), you can generate a traditional, combined, syndromic, or weighted-incidence syndromic combination antibiogram(WISCA). This function also comes with support for R Markdown and Quarto. 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()).

Other: AMR-specific options

The AMR package is customisable, by providing settings that can be set per user or per team. For example, the default interpretation guideline can be changed from EUCAST to CLSI, or a supported language can be set for the whole team (system-language independent) for antibiotic names in a foreign language.

Other: antiviral drugs

This package also provides extensive support for antiviral agents, even though it is not the primary scope of this package. Working with data containing information about antiviral drugs was never easier. Use these functions to get valid properties of antiviral drugs from any input or to clean your input. You can even retrieve drug names and doses from clinical text records, using av_from_text().

as.av() is.av(): Transform Input to an Antiviral Drug ID

av_name() av_cid() av_synonyms() av_tradenames() av_group() av_atc() av_loinc() av_ddd() av_ddd_units() av_info() av_url() av_property(): Get Properties of an Antiviral Drug
