Hi, Stephen:
RTools is not a standard R package. It is a collection of
software tools for building R packages. If you use R much, I highly
recommend you learn about R package development, because I believe doing
so can increase your software development productivity.
However, for this, you do NOT need RTools. For now, please
ignore RTools, and install either Strawberry perl or ActivePerl. I
suggest you go to "http://strawberryperl.com
<http://strawberryperl.com/>" and click on "Download Strawberry Perl
5.12.1.0". This is the version I have. Then do the obvious things to
install it. If it fixed your problem, great. Otherwise, please report
to this list what you've tried, the error you got, and sessionInfo().
Hope this helps.
Spencer
