The *R Language*^{[1]}^{[2]} is a computer programming language developed for data analysis. It is almost identical to an earlier language known as *S*.

A number of different apps have been developed for conducting analyses written in the *R Language*. Somewhat confusingly, the most widely used program for conducting analyses using the R language is also called 'R', and it is used by many of the other apps (e.g., including Displayr and Q). In this documentation, we refer to the app as the *R Console*. The *R Console* can be downloaded from r-project.org.

When Displayr and Q perform calculations in R, they do so by sending them to a server that has the *R Console* on it (see Security and R).
