Frankly, I think Brian was gentle in his criticism of the reviewer. My
first thought when I wrote you privately about RPART and tree, was that I'd
be real suspicious of a reviewer that ignorant. I'd be even more wary of
applying this technique based on the reviewer's dubious
suggestion. Perhaps the reviewer really did mean regression trees, but I
doubt that anyone who ever *used* them would fall into the trap of calling
them "anova trees".
I don't think Brian requires any defending. He seems perfectly capable of
defending himself <g>, but I think your reply was uncalled for. The R user
community owes a huge debt of gratitude to all those like Brian who give
their time freely not only to this list but to the further development of R.
