It's hard to see where the problem is from this information. I would suggest subscribing to and asking this question of the RExcel mailing list (accessible from http://rcom.univie.ac.at/) and providing more detail of what you're trying to do, what is going wrong, error messages (is it R or Excel giving the error?) and so on. For all I know, it may well not be an R issue at all but a problem somewhere in your Excel or VBA setup.
