MIT now has access to a new statistical software package on Athena: R (thanks to licensing from MIT IS&T). R is an open-source, free software environment for statistical computing and graphics with its own internal programming language. More information about the software is available at: http://www.r-project.org/.
Help with R and other statistical software packages is available from the Harvard-MIT Data Center Statistical Consulting Service. Contact a Consultant at http://libraries.mit.edu/askhmdc.
