Thanks for the suggestion.  

I simply did 
R -- vanilla

I tried it again this morning so that I could compare the output.
However, it *worked* fine -- just as I thought it would done
yesterday.  Why it didn't work yesterday is a mystery.

I've had a few other things behaving strangely on this machine so
there might be an OS issue, not an R issue.

Thanks for taking the time.
