[R] Creating a R package for Windows XP

[Prof Brian Ripley]

You have created a source package, and c:/R/rw2010/library is not the 
right place for a source package.  You need to move it somewhere else and 
INSTALL it, as described in the rw-FAQ.  (You need to move it because it 
would be installed into that directory and you are not allowed to clobber 
the sources by doing so.)

Both `Writing R Extensions' and `R Installation and Administration' 
manuals give more details: in particular the latter describes the tools 
you will need to collect.
