Plugins: R Commander Plug-in Packages

Description Details See Also

Description

Plug-ins are R packages that extend the R Command interface.

Details

An R Commander plug-in is an ordinary R package that (1) provides extensions to the R Commander menus is a file named menus.txt located in the package's etc directory; (2) provides call-back functions required by these menus; and (3) in an Models: field in the package's DESCRIPTION file, augments the list of model objects recognized by the R Commander. The menus provided by a plug-in package are merged with the standard Commander menus. It is also possible to remove menus and menu items from the standard Commander menu file or from the files of plug-ins installed before the current one.

Plug-in packages given in the R Commander plugins option (see Commander) are automatically loaded when the Commander starts up. Plug-in packages may also be loaded via the Commander Tools -> Load Rcmdr plug-in(s) menu; a restart of the Commander is required to install the new menus. Finally, loading a plug-in package when the Rcmdr is not loaded will load the Rcmdr and activate the plug-in.

An illustrative R Commander plug-in package, RcmdrPlugin.TeachingDemos, is available on CRAN.

There is also more recent information about writing plug-ins in Fox and Carvalho (2012), “The RcmdrPlugin.survival Package: Extending the R Commander Interface to Survival Analysis,” Journal of Statistical Software, 49:7, 1–32. <http://www.jstatsoft.org/v49/i07>.
