\usage{
bug_drug_combinations(x, col_mo = NULL, minimum = 30,
  FUN = mo_shortname, ...)

\method{format}{bug_drug_combinations}(x, combine_IR = FALSE,
  add_ab_group = TRUE, decimal.mark = getOption("OutDec"),
  big.mark = ifelse(decimal.mark == ",", ".", ","))
}
\arguments{
\item{x}{data with antibiotic columns, like e.g. \code{AMX} and \code{AMC}}

\item{col_mo}{column name of the IDs of the microorganisms (see \code{\link{as.mo}}), defaults to the first column of class \code{mo}. Values will be coerced using \code{\link{as.mo}}.}

\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 Source.}

\item{FUN}{the function to call on the \code{mo} column to transform the microorganism IDs, defaults to \code{\link{mo_shortname}}}

\item{...}{argumments passed on to \code{FUN}}

\item{combine_IR}{logical to indicate whether values R and I should be summed}

\item{add_ab_group}{logical to indicate where the group of the antimicrobials must be included as a first column}

\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.}
}
\description{
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{format} on the result to prettify it to a printable format, see Examples.
}
\details{
The function \code{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. 

The language of the output can be overwritten with \code{options(AMR_locale)}, please see \link{translate}.
