\title{Add Custom Antimicrobials to This Package}
\usage{
add_custom_antimicrobials(x)

clear_custom_antimicrobials()
}
\arguments{
\item{x}{a \link{data.frame} resembling the \link{antibiotics} data set, at least containing columns "ab" and "name"}
}
\description{
With \code{\link[=add_custom_antimicrobials]{add_custom_antimicrobials()}} you can add your own custom antimicrobial drug codes to the \code{AMR} package.
}
\details{
\strong{Important:} Due to how \R works, the \code{\link[=add_custom_antimicrobials]{add_custom_antimicrobials()}} function has to be run in every \R session - added antimicrobials are not stored between sessions and are thus lost when \R is exited.

There are two ways to automate this process:

\strong{Method 1:} Save the antimicrobials to a local or remote file (can even be the internet). To use this method:
\enumerate{
\item Create a data set in the structure of the \link{antibiotics} data set (containing at the very least columns "ab" and "name") and save it with \code{\link[=saveRDS]{saveRDS()}} to a location of choice, e.g. \code{"~/my_custom_ab.rds"}, or any remote location.
\item Set the file location to the \code{AMR_custom_ab} \R option: \code{options(AMR_custom_ab = "~/my_custom_ab.rds")}. This can even be a remote file location, such as an https URL. Since options are not saved between \R sessions, it is best to save this option to the \code{.Rprofile} file so that it will loaded on start-up of \R. To do this, open the \code{.Rprofile} file using e.g. \code{utils::file.edit("~/.Rprofile")}, add this text and save the file:

\if{html}{\out{<div class="sourceCode r">}}\preformatted{# Add custom antibiotic drug codes:
options(AMR_custom_ab = "~/my_custom_ab.rds")
}\if{html}{\out{</div>}}

Upon package load, this file will be loaded and run through the \code{\link[=add_custom_antimicrobials]{add_custom_antimicrobials()}} function.
}

\strong{Method 2:} Save the antimicrobial additions directly to your \code{.Rprofile} file. An important downside is that this requires to load the \code{AMR} package at every start-up. To use this method:
\enumerate{
\item Edit the \code{.Rprofile} file using e.g. \code{utils::file.edit("~/.Rprofile")}.
\item Add a text like below and save the file:

\if{html}{\out{<div class="sourceCode r">}}\preformatted{ # Add custom antibiotic drug codes:
 library(AMR)
 add_custom_antimicrobials(
   data.frame(ab = "TESTAB",
              name = "Test Antibiotic",
              group = "Test Group")
 )
}\if{html}{\out{</div>}}
}

Use \code{\link[=clear_custom_antimicrobials]{clear_custom_antimicrobials()}} to clear the previously added antimicrobials.
}
