Research Computing Support

R by the R Core Team

What is it? R is a free, open source software environment for statistical computing, data management and graphics. While all of its features can be controlled by its programming language, several user interfaces exist that make it easy for non-programmers to use. It 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 is open source software, anyone can use it for almost any purpose. Here are its license details.

Where can I run it? Being free, you can install R on any Linux, Mac or Windows computer. R is 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 its 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 lists addresses for support “mailing lists” and manuals.

Where can I get support? OIT offers Full Support for R. The best web site to ask questions or look up answers regarding R programming is Stack Overflow. The best place to ask questions or look up answers regarding statistical analysis in R is Cross Validated. You can request assistance by calling the OIT HelpDesk at 865-974-9900.
