The following snapshot represents the default window when starting R. The default window is highly similar across platforms, which is why it is not necessary to display all screenshots here. More importantly, most of what is covered will apply to any recent build of R. Advanced readers might be interested in using a more sophisticated development tool such as RStudio available at http://www.rstudio.com/. Because of space limitations, we will not describe it here.
The encompassing window displayed in the picture below, R graphic user interface (RGui), contains a basic graphic user interface. You can see the menu bar on the top of the window. We will look at some of its elements more closely in the following screenshot:
