Brief description of some important panes

The Source pane will be used to code and save your programs. Once code is created you can use File | Save to save your work to an external file, and File | Open to retrieve the saved code.

If you are installing RStudio for the first time nothing may be shown as the fourth pane. However, as you create new programs (as we will later in this chapter), it will appear in the upper right quadrant.

The Console pane provides important feedback and information about your program after it has been run. It will show you any syntax or error messages that have occurred. It is always a best practice to examine the console to make sure you are getting the results you expect, and make sure the console is clear of errors. The console is also the place that you will see a lots of output which has been created from your programs.
We will rely heavily on the View pane. This pane displays formatted output which is run by using the R View command.
The Environment | History | Plots pane is sort of a catch-all pane which changes functions depending upon what which tabs have been selected via the pane layout dialogue. For example, all plots issued by R command are displayed under the Plots tab. Help is always a click away by selecting the Help tab. There is also a useful tab called Packages which will automatically load a package, when a particular package is checked.
