Explain how you can start the R commander GUI?

Start R by double-clicking on the R icon on the desktop, or by clicking on the R icon in the start menu. The R graphical user interface (GUI) will open, containing a single window called the command or console window. The greater-than sign ( > ) is R’s “prompt;” it indicates that R is ready for you to enter commands.

To open the R commander program type at the prompt library(“Rcmdr”) and press return. The R commander window shown below will open.

Note: Graphs will appear in a separate Graphics Device Window. Only the most recent graph will appear.
