   I am embarrassed to have to ask this but can anyone tell me of a Tukey
   multiple comparisons procedure available for R?  I have looked through
   the search page, through the FAQ, and in the index of V&R (1999), and
   I still can't find such a thing.  I see there is a ptukey function and
   a qtukey function but that is as far as I got.  Do I need to roll my
   own?

Doug,

Try qtukey to get the quantile, then divide by sqrt(2) to get the
multiple.
