redundant_packages: Find redundant packages

Description

Find redundant packages

Usage

redundant_packages(packages)

Arguments

packages

list of package names.

Value

A named list of packages names, where each value is a vector of packages already loading the corresponding package.

#grid does not have be loaded since gridGraphics already does so.
redundant_packages(c("gridGraphics","grid"))
# }
