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 class '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,AMXandAMC- col_mo
column name of the names or codes of the microorganisms (see
as.mo()) - the default is the first column of classmo. Values will be coerced usingas.mo().- FUN
the function to call on the
mocolumn to transform the microorganism codes - the default ismo_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 - the default is the current system language (see
get_AMR_locale()) and can also be set with the package optionAMR_locale. Uselanguage = NULLorlanguage = ""to prevent translation.- minimum
the minimum allowed number of available (tested) isolates. Any isolate count lower than
minimumwill returnNAwith a warning. The default number of30isolates 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 - the default is
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.intervaldecimals before (hencebig) the decimal point.
Value
The function bug_drug_combinations() returns a data.frame with columns "mo", "ab", "S", "SDD", "I", "R", and "total".
Details
The function format() calculates the resistance per bug-drug combination and returns a table ready for reporting/publishing. Use combine_SI = TRUE (default) to test R vs. S+I and combine_SI = FALSE to test R+I vs. S. This table can also directly be used in R Markdown / Quarto without the need for e.g. knitr::kable().
