The **Rcmdr** (R Commander) package is a platform-independent graphical user interface (GUI) for R, based on the **tcltk** package (distributed with R) and on the Tcl/Tk GUI builder. Although GUIs for statistical software have serious limitations, the R Commander provides new and casual users of R the ability to access some of R's capabilities though an intuitive point-and-click interface. Designed originally with basic-statistics courses in mind, the R Commander has expanded beyond that purpose to encompass extensive facilities for fitting linear, generalized-linear, and some other statistical models. The R Commander is also extensible through “plug-in packages,” and a number of such packages have been contributed to the Comprehensive R Archive Network (CRAN). Along with the basic use of the R Commander, this presentation will demonstrate one such package, the **RcmdrPlugin.survival** package, which provides a GUI for many of the facilities of the **survival** package for survival analysis, which in turn is part of the standard R distribution.
