The R website

www.r-project.org is the website you should visit first. This website has them all you need. Sadly you don't even need to come to my blog anymore once you get there.

• Downloading R

If you are an ordinary person, I am 90% sure you want the software in your hand first. Forget "Always read the instruction first.", and let us just enjoy the happiness of possessing free software.

On the left menu at the main page, there is a link "CRAN". Click it that lead you to all the mirror sites all over the world. Choose one of those countries, then you'll see "download and install R". Three versions of R for Linux, Windows and Mac are available. Next page for Windows, for example, has "base" and "contrib" to choose. Click "base" then you'll get "Download R 2.8.1 for Windows (34 megabytes)" that is 32-bit Window version of R.
