Functions to query and manipulate the package cache — pkg_cache_summary • pkgcache

pkg_cache_summary() returns a short summary of the state of the cache, e.g. the number of files and their total size. It returns a named list.

pkg_cache_summary(cachepath = NULL)

pkg_cache_list(cachepath = NULL)

pkg_cache_find(cachepath = NULL, ...)

pkg_cache_get_file(cachepath = NULL, target, ...)

pkg_cache_delete_files(cachepath = NULL, ...)

pkg_cache_add_file(cachepath = NULL, file, relpath = dirname(file), ...)

Arguments

cachepath: Path of the cache. By default the cache directory is in pkgcache, within the user's cache directory. See tools::R_user_dir().
...: Extra named arguments to select the package file.
target: Path where the selected file is copied.
file: File to add.
relpath: The relative path of the file within the cache.
