Determine Bug-Drug Combinations — bug_drug

Determine antimicrobial resistance (AMR) of all bug-drug combinations in your data set where at least 30 (default) isolates are available per species. Use format() on the result to prettify it to a publishable/printable format, see Examples.

Usage

bug_drug_combinations(x, col_mo = NULL, FUN = mo_shortname, ...)

# S3 method for bug_drug_combinations
format(
  x,
  translate_ab = "name (ab, atc)",
  language = get_AMR_locale(),
  minimum = 30,
  combine_SI = TRUE,
  add_ab_group = TRUE,
  remove_intrinsic_resistant = FALSE,
  decimal.mark = getOption("OutDec"),
  big.mark = ifelse(decimal.mark == ",", ".", ","),
  ...
)

Arguments

x: a data set with antibiotic columns, such as amox, AMX and AMC
col_mo: column name of the names or codes of the microorganisms (see as.mo()), defaults to the first column of class mo. Values will be coerced using as.mo().
FUN: the function to call on the mo column to transform the microorganism codes, defaults to mo_shortname()
...: arguments passed on to FUN
translate_ab: a character of length 1 containing column names of the antibiotics data set
language: language of the returned text, defaults to system language (see get_AMR_locale()) and can also be set with the option AMR_locale. Use language = NULL or language = "" to prevent translation.
minimum: the minimum allowed number of available (tested) isolates. Any isolate count lower than minimum will return NA with a warning. The default number of 30 isolates is advised by the Clinical and Laboratory Standards Institute (CLSI) as best practice, see Source.
combine_SI: a logical to indicate whether values S and I should be summed, so resistance will be based on only R, defaults to TRUE
add_ab_group: a logical to indicate where the group of the antimicrobials must be included as a first column
remove_intrinsic_resistant: logical to indicate that rows and columns with 100% resistance for all tested antimicrobials must be removed from the table
decimal.mark: the character to be used to indicate the numeric decimal point.
big.mark: character; if not empty used as mark between every big.interval decimals before (hence big) the decimal point.

Value

The function bug_drug_combinations() returns a data.frame with columns "mo", "ab", "S", "I", "R" and "total".

Details

The function format() calculates the resistance per bug-drug combination. Use combine_SI = TRUE (default) to test R vs. S+I and combine_SI = FALSE to test R+I vs. S.
