The R Commander is a graphical user interface (GUI) for R, designed to support basic statistical analysis. Unlike S-PLUS, R does not come with a built-in statistical GUI, but it includes tools for creating GUIs. The R Commander, based on the Tcltk package, provides a user-friendly interface for performing statistical analyses. Its design objectives include ease of use, cross-platform compatibility, and extensibility. The GUI supports various statistical functionalities, from basic data summaries and graphs to more advanced models like linear and generalized linear models. It uses a menu/dialog-box interface, with each selection generating R commands that are recorded in a script window and echoed in an output window. Data sets are managed as R data frames, and the GUI allows users to read data from text files, import data from other packages, or use data from R packages. The R Commander also includes features for fitting statistical models, creating graphs, and managing output. The paper discusses the design and development of the R Commander, its features, and how it can be extended. It aims to introduce the R Commander to students and provide insights into its functionality and potential for future enhancements.The R Commander is a graphical user interface (GUI) for R, designed to support basic statistical analysis.
