Delete old cache files

Usage

qgis_delete_old_cachefiles(
  type = "all",
  age_days = NULL,
  quiet = FALSE,
  startup = FALSE
)

type: A string; either "all", "package" or "help". This selects the type of cache files to delete.
age_days: A number that expresses a cache file's age that must be exceeded for it to be deleted, with age defined as days elapsed since the file's last modification date. The default value of 90 days can also be changed with the option qgisprocess.cachefiles_days_keep or the environment variable R_QGISPROCESS_CACHEFILES_DAYS_KEEP.
quiet: Use FALSE to display more information, possibly useful for debugging.
startup: Logical. Is this command being run while loading the package?

Note that a currently used package cache file will never be deleted.

This function is called when loading the package.

This is an internal function.
