pkgdiff (version 0.2.1)

pkg_cache: Queries the Package Cache

Description

The pkg_cache function queries the package cache, and returns information on which packages are included in the cache. The function also returns the last version of the package cached.

Usage

pkg_cache(pkgs = NULL)

Value

An data frame showing the package name and latest package version stored in the cache. If the package is not stored in the cache, the package version will be NA. The "Last Update" time stamp is the last day and time the cache was updated.

Arguments

pkgs

A vector of package names to retrieve cache information about. Default is NULL, which means to return all packages in the cache.

Details

The pkgdiff cache is used to speed up pkgdiff functions. Information about each package is pre-processed and stored in the cache on Github. The functions then retrieve this pre-processed information instead of pulling packages down from CRAN. To learn more about the cache, refer to vignette('pkgdiff-cache').
