With add_custom_antimicrobials() you can add your own custom antimicrobial drug names and codes.
Arguments
- 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, which is the preferred method. To use this method:
- 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.
- Set the file location to the package option - AMR_custom_ab:- 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- .Rprofilefile so that it will be loaded on start-up of R. To do this, open the- .Rprofilefile using e.g.- utils::file.edit("~/.Rprofile"), add this text and save the file:- # 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:
- Edit the - .Rprofilefile using e.g.- utils::file.edit("~/.Rprofile").
- Add a text like below and save the file: - # 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.
