#' Add Custom Antimicrobials
|
|
#'
|
|
#' With [add_custom_antimicrobials()] you can add your own custom antimicrobial drug names and codes.
|
|
#' @param x a [data.frame] resembling the [antibiotics] data set, at least containing columns "ab" and "name"
|
|
#' @details **Important:** Due to how \R works, the [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 circumvent this and automate the process of adding antimicrobials:
|
|
#'
|
|
#' **Method 1:** Using the package option [`AMR_custom_ab`][AMR-options], which is the preferred method. To use this method:
|
|
#'
|
|
#' 1. Create a data set in the structure of the [antibiotics] data set (containing at the very least columns "ab" and "name") and save it with [saveRDS()] to a location of choice, e.g. `"~/my_custom_ab.rds"`, or any remote location.
|
|
#'
|
|
#' 2. Set the file location to the package option [`AMR_custom_ab`][AMR-options]: `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 `.Rprofile` file so that it will be loaded on start-up of \R. To do this, open the `.Rprofile` file using e.g. `utils::file.edit("~/.Rprofile")`, add this text and save the file:
|
|
#'
|
|
#' ```r
|
|
#' # Add custom antimicrobial codes:
|
|
#' options(AMR_custom_ab = "~/my_custom_ab.rds")
|
|
#' ```
|
|
#'
|
|
#' Upon package load, this file will be loaded and run through the [add_custom_antimicrobials()] function.
|
|
#'
|
|
#' **Method 2:** Loading the antimicrobial additions directly from your `.Rprofile` file. Note that the definitions will be stored in a user-specific \R file, which is a suboptimal workflow. To use this method:
|
|
#'
|
|
#' 1. Edit the `.Rprofile` file using e.g. `utils::file.edit("~/.Rprofile")`.
|
|
#'
|
|
#' 2. Add a text like below and save the file:
|
|
#'
|
|
#' ```r
|
|
#' # Add custom antibiotic drug codes:
|
|
#' AMR::add_custom_antimicrobials(
|
|
#' data.frame(ab = "TESTAB",
|
|
#' name = "Test Antibiotic",
|
|
#' group = "Test Group")
|
|
#' )
|
|
#' ```
|
|
#'
|
|
#' Use [clear_custom_antimicrobials()] to clear the previously added antimicrobials.
|
|
#' @seealso [add_custom_microorganisms()] to add custom microorganisms.
|
|
#' @rdname add_custom_antimicrobials

#' suppressWarnings(

#' as.ab("testab")
|
|
#' )
|

#'

#' # now add a custom entry - it will be considered by as.ab() and
|
|
#' # all ab_*() functions

|
