Prof Ripley:

Thank you for the help.

   - I used the "manual" option because it was suggested in some postings
   because it shows the parameters being used.  The behavior was the same with
   and without the "manual" option (I needed to use ESC to get out).
   - Would there be some limitation in my hardware that would prevent the
   snow package to work?
   - Is there some sort of diagnostics in the snow package that can report
   setup difficulties?
   - Are you saying my version of R is obsolete at 2/29/12?  I could try to
   use the new version of R to see if that makes a difference.  But wouldn't
   the snow code work the same since it hasn't been updated?
   - I can look at the package parallel.  I used snow because of an example
   in the text "The Art of R Programming".

Jeff
