## Latest revision as of 19:20, 9 October 2008

This page is to serve as a resource for the UConn community (especially EEB) to encourage the use of R in data analysis. It is also the resource site for the EEB Short Course in R, entitled "Introduction to R."

## The R project for Statistical Computing

R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS. To download R, please choose your preferred CRAN mirror (http://cran.r-project.org/mirrors.html).

## UConn UseR Group

We also have a google group to facilitate discussions, questions, and anything else that comes to mind. Check it out at: http://groups.google.com/group/UConn-useRs or subscribe by sending an email to UConn-useRs-subscribe@googlegroups.com

## Short Course

In the September/October 2008, we'll be offering a short course in R to beginners.
The course will be on **Fridays from 2-3:30 in TLS 301 from September 5th through October 17th.**

The results of the survey to pick a time and of student R-status are here .
