Oops -- I should have tested it without libraries loaded :-) The conflict must be with the HH package. I tested the example again using all the packages required by HH and do get the correct results, but once the HH package is loaded, the TukeyHSD function returns "height" and the plot command gives the error described previously.
Should I report this bug directly to the authors of the HH package or file a new bug report under HH? Thanks!
