1.4) Description (cont'd)

The central point of reference for R is the web site http://www.r-project.org/. There is then a “Comprehensive R Archive Network” (CRAN) of servers around the world, which are identical, authentic sources of R (R Development Core Team 2007) and the contributed packages for R. For downloading any of these, you will be asked to select your local server. If you’re installing R on your own computer, the main set-up programme for Windows will be called something like R-3.0.2-win.exe – click on it, choose “Run” and follow the instructions.
