package

package name

additional arguments passed to packageDescription.

integer: the number of dependencies

Details

The recursive and reverse arguments are perhaps of most interest. recursive details the number of dependencies of the package, including those that are dependencies of dependencies. reverse details the number of packages that depend on the package, which may be an indicator of a high quality package. This function uses the function from the tools package.
