localPackages: Install and update packages from a local source easily under Windows

Description

Usage

localPackages(basedir = "d:/R", url = paste("file:", basedir, "/bin/windows/contrib", sep = ""), ask.update = TRUE)

Arguments

basedir
The base directory of the local installation files
url
The whole path, or url, to use for installation. If provided, it overrides basedir
ask.update
If ask.update is TRUE, the function also update old packages. Otherwise, it only installs new ones.

Value
