ab_property {AMR}

Get Properties of an Antibiotic

Description

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().

Usage

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

ab_cid(x, ...)

ab_synonyms(x, ...)

ab_tradenames(x, ...)

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

ab_atc(x, only_first = FALSE, ...)

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

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

ab_loinc(x, ...)

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

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

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

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

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

set_ab_names(
  data,
  ...,
  property = "name",
  language = get_AMR_locale(),
  snake_case = NULL
)

Arguments

x

any (vector of) text that can be coerced to a valid antibiotic drug code with as.ab()

language

language of the returned text - the default is the current system language (see get_AMR_locale()) and can also be set with the package option 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".

...

in case of set_ab_names() and data is a data.frame: columns to select (supports tidy selection such as column1:column4), otherwise other arguments passed on to as.ab()

only_first

a logical to indicate whether only the first ATC code must be returned, with giving preference to J0-codes (i.e., the antimicrobial drug group)

administration

way of administration, either "oral" or "iv"

open

browse the URL using utils::browseURL()

property

one of the column names of one of the antibiotics data set: vector_or(colnames(antibiotics), sort = FALSE).

data

a data.frame of which the columns need to be renamed, or a character vector of column names

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 (⁠_⁠)

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.

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

# all properties:

ab_synonyms("AMX")
ab_tradenames("AMX")
ab_group("AMX")
ab_atc_group1("AMX")
ab_atc_group2("AMX")
ab_url("AMX")

# smart lowercase transformation
ab_name(x = c("AMC", "PLB"))
ab_name(x = c("AMC", "PLB"), tolower = TRUE)

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

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")
ab_group("J01CA01")
ab_loinc("ampicillin")
ab_name("21066-6")
ab_name(6249)
ab_name("J01CA01")

# 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))
colnames(set_ab_names(example_isolates, NIT:VAN))

if (require("dplyr")) {
  example_isolates %>%
    set_ab_names()

  # this does the same:
  example_isolates %>%
    rename_with(set_ab_names)

  # set_ab_names() works with any AB property:
  example_isolates %>%
    set_ab_names(property = "atc")

  example_isolates %>%
    set_ab_names(where(is.sir)) %>%
    colnames()

  example_isolates %>%
    set_ab_names(NIT:VAN) %>%
    colnames()
