character, indicating the type of package to download and install.

Possible values are "source", "mac.binary.leopard" and "win.binary": the binary types can be listed and downloaded but not installed on other platforms.

The default is the appropriate binary type on Windows and on the CRAN binary OS X distribution, otherwise "source". For the platforms where binary packages are the default, an alternative is "both" which means ‘try binary if available, otherwise try source’. (This will only choose the binary package if its version number is no older than the source version. In interactive use it will ask before attempting to install source packages.)
