R & RStudio

What is it? R is a free, open source software environment for statistical computing, data management and graphics. While it includes a simple code editor, it can be controlled through many other packages. The most popular way to run R is through RStudio, a free and open source program which includes a code editor, debugging, and visualization tools. R is very extensible and supports a wide range of methods. However, its data usually must fit into your computer’s main memory, limiting the size of data sets it can analyze.

What can I use if for? Since R and RStudio are open source software, anyone can use them for almost any purpose. Here are the license details for R and RStudio.

Where can I run it? Being free, you can install R and RStudio, on any Linux, Mac or Windows computer. They are both also available on OIT’s  Apps@UT server, and on the computers in the OIT public computer labs. There is no simultaneous user limit for their use. People with extreme computational requirements can also run R batch jobs on JICS’ Advanced Computing Facility.

How can I learn it? OIT offers workshops each semester and there are a set of two-minute tutorials at the  “twotorials” web site. The main R web site provides links to reference materials including  FAQs, manuals, support “mailing lists”, and books.
