\arguments{
2022-08-27 20:49:37 +02:00
\item{x}{a data set with antibiotic columns, such as \code{amox}, \code{AMX} and \code{AMC}}
2019-08-25 22:53:22 +02:00
\item{col_mo}{column name of the IDs of the microorganisms (see \code{\link[=as.mo]{as.mo()}}), defaults to the first column of class \code{\link{mo}}. Values will be coerced using \code{\link[=as.mo]{as.mo()}}.}
2019-08-25 22:53:22 +02:00
2021-06-01 15:33:06 +02:00
\item{FUN}{the function to call on the \code{mo} column to transform the microorganism codes, defaults to \code{\link[=mo_shortname]{mo_shortname()}}}
2019-09-23 13:53:50 +02:00
2019-09-25 15:43:22 +02:00
\item{...}{arguments passed on to \code{FUN}}
2021-05-12 18:15:03 +02:00
\item{translate_ab}{a \link{character} of length 1 containing column names of the \link{antibiotics} data set}
2019-09-25 15:43:22 +02:00
\item{language}{language of the returned text, defaults to system language (see \code{\link[=get_AMR_locale]{get_AMR_locale()}}) and can also be set with \code{getOption("AMR_locale")}. Use \code{language = NULL} or \code{language = ""} to prevent translation.}
2019-09-25 15:43:22 +02:00
\item{minimum}{the minimum allowed number of available (tested) isolates. Any isolate count lower than \code{minimum} will return \code{NA} with a warning. The default number of \code{30} isolates is advised by the Clinical and Laboratory Standards Institute (CLSI) as best practice, see \emph{Source}.}
2021-05-12 18:15:03 +02:00
\item{combine_SI}{a \link{logical} to indicate whether all values of S and I must be merged into one, so the output only consists of S+I vs. R (susceptible vs. resistant). This used to be the argument \code{combine_IR}, but this now follows the redefinition by EUCAST about the interpretation of I (increased exposure) in 2019, see section 'Interpretation of S, I and R' below. Default is \code{TRUE}.}
2019-09-23 13:53:50 +02:00
2021-05-12 18:15:03 +02:00
\item{combine_IR}{a \link{logical} to indicate whether values R and I should be summed}
2019-08-27 22:41:09 +02:00
2021-05-12 18:15:03 +02:00
\item{add_ab_group}{a \link{logical} to indicate where the group of the antimicrobials must be included as a first column}
2019-08-27 23:00:00 +02:00
2021-05-12 18:15:03 +02:00
\item{remove_intrinsic_resistant}{\link{logical} to indicate that rows and columns with 100\% resistance for all tested antimicrobials must be removed from the table}
2019-09-25 15:43:22 +02:00
2019-09-23 13:53:50 +02:00
\item{decimal.mark}{the character to be used to indicate the numeric
decimal point.}
\item{big.mark}{character; if not empty used as mark between every
\code{big.interval} decimals \emph{before} (hence \code{big}) the
decimal point.}
2019-08-25 22:53:22 +02:00
}
\value{
The function \code{\link[=bug_drug_combinations]{bug_drug_combinations()}} returns a \link{data.frame} with columns "mo", "ab", "S", "I", "R" and "total".

\description{
2021-07-04 15:26:50 +02:00
Determine antimicrobial resistance (AMR) of all bug-drug combinations in your data set where at least 30 (default) isolates are available per species. Use \code{\link[=format]{format()}} on the result to prettify it to a publishable/printable format, see \emph{Examples}.
2019-08-25 22:53:22 +02:00
}
\details{
The function \code{\link[=format]{format()}} calculates the resistance per bug-drug combination. Use \code{combine_IR = FALSE} (default) to test R vs. S+I and \code{combine_IR = TRUE} to test R+I vs. S.
