R: Select Package Repositories

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 and tcltk and an X server are available, use a Tk widget, or if under the AQUA interface use a MacOS X widget, otherwise use a text list in the console.
`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.

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

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.

### See Also

`chooseCRANmirror`, `install.packages`.
