[R] Error with "compiler" and "caret" packages

[Jeff Hughes]

That sounds like a good thing to check, but what permissions should I be
checking? I'm not very familiar with how the compiler works -- is it
creating temp files somewhere that I should check? If you have a suggestion
for a directory or two that seem like good candidates, I can play around
with the permissions, but I don't really want to start messing around with
my entire C: drive or whatever.

Thanks,
Jeff
