A Tiny Handbook of R (SpringerBriefs in Statistics)

Buy
R has a command-line interface, not a point-and-click GUI (graphical user interface).1 A GUI is easier to learn, and is the best way to interact with graphics. But you can be more expressive with command lines. The commands have a syntax. It’s a language, and like any language the more fluent you are the more expressive you can be. Ultimately it gives you a wider range of possibilities than a GUI.

At some stage you will have to write a program or ‘‘script’’, several lines of commands. This seems laborious at first but becomes rewarding as you develop scripts you can re-use. It is quite possible for example for an R script to read data, fit some models, generate some tables and graphics, and even typeset the results. Then you can reproduce the whole process with a single keypress. You can regenerate the whole paper with different data. You can send your work to a colleague so they can see your results and replay the process by which you obtained them.
