get_package_version: Query Installed Package Version

Description

packageVersion converts to class package_version, which then again would need to be converted for compareVersion. So this is a modified copy of packageVersion skipping the conversion to package_version.

Usage

get_package_version(x, lib_loc = NULL)

Arguments

x

A character giving the package name.

lib_loc

See argument lib.loc in packageDescription.

Value

A character giving the package version.
