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).
