Installing R

Go to

http://cran.cnr.berkeley.edu/

click on

Windows(95 and later)

click on

base

click on

R-2.5.1-win32.exe

and then say you want to Run the file.

It will probably come back and say it is an unverified publisher, again say you want to Run the file.

After this just follow the instructions on the installation wizard.

After this there should be an R 2.4.1 icon on your desktop.

Click on it

At the > prompt type

> getwd()

[1] "C:/Program Files/R/R-2.4.1"

This means this is your working directory, it is where R will go first to look for source code or datafiles. I recommend going to this directory and creating two new folders, call one “datasets” and the other “sourcecode”. This is not necessary for R to work, it will just help you stay more organized.
