user_log_dir(
  appname = NULL,
  appauthor = appname,
  version = NULL,
  opinion = TRUE,
  expand = TRUE,
  os = NULL
)

Arguments

appname

is the name of application. If NULL, just the system directory is returned.

appauthor

(only required and used on Windows) is the name of the appauthor or distributing body for this application. Typically it is the owning company name. This falls back to appname.

version

is an optional version path element to append to the path. You might want to use this if you want multiple versions of your app to be able to run independently. If used, this would typically be "<major>.<minor>". Only applied when appname is not NULL.

opinion

(logical) can be FALSE to disable the appending of ‘Logs’ to the base app data dir for Windows, and ‘log’ to the base cache dir for Unix. See discussion below.

expand

If TRUE (the default) will expand the R_LIBS specifiers with their equivalents. See R_LIBS() for list of all possibly specifiers.

os

Operating system whose conventions are used to construct the requested directory. Possible values are "win", "mac", "unix". If NULL (the default) then the current OS will be used.

Details

On Windows the only suggestion in the MSDN docs is that local settings go in the CSIDL_LOCAL_APPDATA directory.

Opinion

This function appends ‘Logs’ to the CSIDL_LOCAL_APPDATA value for Windows and appends ‘log’ to the user cache dir for Unix. This can be disabled with the opinion = FALSE option.
