File permissions? (it is possible to set them so that files can be
read by anyone except the user...)
How exactly did you install R, and are there any other clues upon
I get, BTW
Error: could not find function "aa"

One other thing that can cause trouble is networked directories. Files
that are physically on another machine can sometimes not be accessed
by root on the local machine.
