}
\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]{as.mo()}}), defaults to the first column of class \code{\link{mo}}. Values will be coerced using \code{\link[=as.mo]{as.mo()}}.}

\item{info}{print progress}

\item{rules}{a character vector that specifies which rules should be applied. Must be one or more of \code{"breakpoints"}, \code{"expert"}, \code{"other"}, \code{"all"}, and defaults to \code{c("breakpoints", "expert")}. The default value can be set to another value using e.g. \code{options(AMR.eucast_rules = "all")}.}

\item{verbose}{a logical to turn Verbose mode on and off (default is off). In Verbose mode, the function does not apply rules to the data, but instead returns a data set in logbook form with extensive info about which rows and columns would be effected and in which way.}

\item{...}{column name of an antibiotic, please see section \emph{Antibiotics} below}
}
\value{
The input of \code{x}, possibly with edited values of antibiotics. Or, if \code{verbose = TRUE}, a \link{data.frame} with all original and new values of the affected bug-drug combinations.
}
\description{
Apply susceptibility rules as defined by the European Committee on Antimicrobial Susceptibility Testing (EUCAST, \url{http://eucast.org}), see \emph{Source}. This includes (1) expert rules and intrinsic resistance and (2) inferred resistance as defined in their breakpoint tables.

To improve the interpretation of the antibiogram before EUCAST rules are applied, some non-EUCAST rules are applied at default, see Details.
}
\details{
\strong{Note:} This function does not translate MIC values to RSI values. Use \code{\link[=as.rsi]{as.rsi()}} for that. \cr
\strong{Note:} When ampicillin (AMP, J01CA01) is not available but amoxicillin (AMX, J01CA04) is, the latter will be used for all rules where there is a dependency on ampicillin. These drugs are interchangeable when it comes to expression of antimicrobial resistance.

Before further processing, two non-EUCAST rules about drug combinations can be applied to improve the efficacy of the EUCAST rules. These rules are:
\enumerate{
\item A drug \strong{with} enzyme inhibitor will be set to S if the drug \strong{without} enzyme inhibitor is S
\item A drug \strong{without} enzyme inhibitor will be set to R if the drug \strong{with} enzyme inhibitor is R
}

These rules are not applied at default, since they are not approved by EUCAST. To use these rules, use \code{eucast_rules(..., rules = "all")}, or set the default behaviour of the \verb{[eucast_rules()]} function with \code{options(AMR.eucast_rules = "all")} (or any other valid input value(s) to the \code{rules} parameter).

The file containing all EUCAST rules is located here: \url{https://github.com/msberends/AMR/blob/master/data-raw/eucast_rules.tsv}.
}
\section{Antibiotics}{

To define antibiotics column names, leave as it is to determine it automatically with \code{\link[=guess_ab_col]{guess_ab_col()}} or input a text (case-insensitive), or use \code{NULL} to skip a column (e.g. \code{TIC = NULL} to skip ticarcillin). Manually defined but non-existing columns will be skipped with a warning.

The following antibiotics are used for the functions \code{\link[=eucast_rules]{eucast_rules()}} and \code{\link[=mdro]{mdro()}}. These are shown below in the format '\strong{antimicrobial ID}: name (\href{https://www.whocc.no/atc/structure_and_principles/}{ATC code})', sorted by name:

\section{Maturing lifecycle}{

\if{html}{\figure{lifecycle_maturing.svg}{options: style=margin-bottom:5px} \cr}
The \link[=lifecycle]{lifecycle} of this function is \strong{maturing}. The unlying code of a maturing function has been roughed out, but finer details might still change. Since this function needs wider usage and more extensive testing, you are very welcome \href{https://github.com/msberends/AMR/issues}{to suggest changes at our repository} or \link[=AMR]{write us an email (see section 'Contact Us')}.
}

\section{Reference data publicly available}{

All reference data sets (about microorganisms, antibiotics, R/SI interpretation, EUCAST rules, etc.) in this \code{AMR} package are publicly and freely available. We continually export our data sets to formats for use in R, SPSS, SAS, Stata and Excel. We also supply flat files that are machine-readable and suitable for input in any software program, such as laboratory information systems. Please find \href{https://msberends.github.io/AMR/articles/datasets.html}{all download links on our website}, which is automatically updated with every code change.
