You _will_ find it in the rw-FAQ, as mentioned in the posting guide and by 
Patrick!

It is actually very easy, just add

HOME="c:\Documents and Settings\Giraudoux"

to the end of target in the shortcut you use to start R.  If that is too 
difficult, Mike Prager's comments are way too advanced.

PLEASE don't post inaccurate versions of information that is in the FAQs:  
at least become familiar with FAQ yourself and ask your readers to
familiarize themselves if you want to amplify the entries.
