Application Directories: Determine Where to Save Data, Caches, and Logs

An easy way to determine which directories on the users computer you should use to save data, caches and logs. A port of Python's 'Appdirs' (<https://github.com/ActiveState/appdirs>) to R.



R-CMD-check CRAN

rappdirs is a port of appdirs to R. It lets you find the appropriate directory to save caches, logs, and data, on Linux, Mac, and Windows. It allows you to store files that need to shared across R sessions in a way that aligns with the CRAN policies.


What directory should your app use for storing user data? If running on Mac OS X, you should use:

~/Library/Application Support/<AppName>

If on Windows (at least English Win XP) that should be:

C:\Documents and Settings\<User>\Application Data\Local Settings\<AppAuthor>\<AppName>

or possibly:

C:\Documents and Settings\<User>\Application Data\<AppAuthor>\<AppName>

for roaming profiles) but that is another story.

On Linux (and other Unices) the dir, according to the XDG spec (and subject to some interpretation), is either:


or possibly:



This kind of thing is what rappdirs is for. rappdirs will help you choose an appropriate:

  • user data dir (user_data_dir())
  • user config dir (user_config_dir())
  • user cache dir (user_cache_dir())
  • site data dir (site_data_dir())
  • user log dir (user_log_dir())

For example, on Mac:

appname <- "SuperApp"
appauthor <- "Acme"
user_config_dir(appname, appauthor)
#> [1] "~/Library/Application Support/SuperApp"
user_data_dir(appname, appauthor)
#> [1] "~/Library/Application Support/SuperApp"
site_data_dir(appname, appauthor)
#> [1] "/Library/Application Support/SuperApp"
user_cache_dir(appname, appauthor)
#> [1] "~/Library/Caches/SuperApp"
user_log_dir(appname, appauthor)
#> [1] "~/Library/Logs/SuperApp"
