see "setwd".
Alternatively, you can have your CGI copy the R file(s) with commands to the
newly created directory, and run in there.

If your concern is one user deleting/modifying another user's data, I'd
just
use setwd: it is simpler and cleaner.
We use a somewhat similar approach for our web-based applications
(www.asterias.info), which use R, and create a temporary directory for every
request.
