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.
