It did! I had a mean object in the current workspace. Once it was deleted, the argument works without a glitch. Sorry for being late with this feedback but I've been isolated for a bunch of hours. I can reproduce the problem by recreating a mean object. Errors depend on the type of object created and calling explicitly the argument as per the following command (proposed by JiHO) doesn't help > cast(aqm, month ~ variable, fun.aggregate=mean) Could it we advisable that cast, melt or whatever function we deal with throws an more informative error message when this kind of conflicts occur? I am guessing this is a pretty frequent situation, so if it is not done there must be a number of good reasons! Just my two cents!
