A common mistake, but as you found, a mistake nonetheless. This is why I 
recommended you look at 'R Installation and Administration' section 5.1. 
There are specific instructions there that explain how you install 
packages, and in Appendix F there are instructions on getting various 
tools you will need on Windows in order to do so.

These instructions are rather terse, but note that if you want to 
install packages on Windows, you have to follow what they say _exactly_. 
This can be a daunting task the first time through, but once you know 
what to do, it is really quite simple.

HTH,

Jim
