Retrieve Names of All Installable Packages

Share:

Description

The APT Package Management system uses a data-rich caching structure. This accessor function returns the names of installable packages for a given regular expression.

Usage

1
getPackages(regexp = ".")

Arguments

regexp

A regular expression for the package name(s) with a default of all (".").

Details

Note that the package lookup uses regular expressions. If only a single package is desired, append a single $ to terminate the expression. Ie r-cran-rcpp$ will not return results for r-cran-rcpparmadillo and r-cran-rcppeigen.

Value

A data frame with columns containing the package name, the installed version (or NA if not installed) and the section it is installed in (or NA).
