Add Custom Antimicrobials to This Package

With add_custom_antimicrobials() you can add your own custom antimicrobial drug codes to the AMR package.

Usage

add_custom_antimicrobials(x)

clear_custom_antimicrobials()

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 automate this process:

Method 1: Save the antimicrobials to a local or remote file (can even be the internet). 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 AMR_custom_ab R option: 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 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:
```
# Add custom antibiotic drug 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: Save the antimicrobial additions directly to your .Rprofile file. An important downside is that this requires to load the AMR package at every start-up. To use this method:

Edit the .Rprofile file using e.g. utils::file.edit("~/.Rprofile").

Add a text like below and save the file:

 # Add custom antibiotic drug codes:
 library(AMR)
 add_custom_antimicrobials(
   data.frame(ab = "TESTAB",
              name = "Test Antibiotic",
              group = "Test Group")
 )

Use clear_custom_antimicrobials() to clear the previously added antimicrobials.

Examples

# \donttest{

# returns NA and throws a warning (which is now suppressed):
suppressWarnings(
  as.ab("testab")
)

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

    name = "Test Antibiotic",
    # you can add any property present in the
    # 'antibiotics' data set, such as 'group':
    group = "Test Group"
  )
)
#> ℹ Added one record to the internal antibiotics data set.

# "testab" is now a new antibiotic:
as.ab("testab")
#> Class 'ab'
#> [1] TESTAB
ab_name("testab")
#> [1] "Test Antibiotic"
ab_group("testab")
#> [1] "Test Group"
