[Rd] trace an Rd conversion error in R cmd check

Hi, Josh:

       Have you had a recent version that passed "R CMD check"?  If yes, 
I suggest you save your recent changes then revert to that earlier 
version and add your recent changes back in again one at a time.  I've 
done that many times.  (It's also a major reason I make changes as small 
as I can and run "R CMD check" after each one.  Then if I get something 
like this I can't figure out, there aren't many changes to scan through 
to find the problem.)

       Hope this helps.
