setRepositories {utils}R Documentation

Select Package Repositories

Description

Interact with the user to choose the package repositories to be used.

Usage

setRepositories(graphics = getOption("menu.graphics"), ind = NULL)

Arguments

graphics Logical. If true, use a graphical list: on Windows or Mac OS X GUI use a list box, and on a Unix-alike if tcltk and an X server are available, use Tk widget. Otherwise use a text menu.
ind NULL or a vector of integer indices, which have the same effect as if they were entered at the prompt for graphics=FALSE.

Details

The default list of known repositories is stored in the file ‘R_HOME/etc/repositories’. That file can be edited for a site, or a user can have a personal copy in ‘HOME/.R/repositories’ which will take precedence.

A Bioconductor mirror can be selected by setting options("BioC_mirror"): the default value is "http://www.bioconductor.org".

The items that are preselected are those that are currently in options("repos") plus those marked as default in the list of known repositories.

The list of repositories offered depends on the setting of option "pkgType" as some repositories only offer a subset of types (e.g. only source packages or not Mac OS X binary packages). Further, for binary packages some repositories (notably R-Forge) only offer packages for the current or recent versions of R.

This function requires the R session to be interactive unless ind is supplied.

Value

This function is invoked mainly for its side effect of updating options("repos"). It returns (invisibly) the previous repos options setting (as a list with component repos) or NULL if no changes were applied.
