Value

CRAN.views returns an object of class "ctvlist" of the available task views whose elements are of class "ctv". install.views has no return value.

Details

install.views queries the file Views.rds located at the src/contrib directory of repos and then simply calls install.packages to install the packages associated with the view specified. For each view it can be specified whether all packages or only the core packages should be installed.

CRAN.views returns the names of the task views currently available in the file Views.rds.

For a closer description of the arguments see als install.packages.
