Im not sure i know what you mean by "data sets with differing numbers/types of 
variables". A joinExisting has to have homogenous sets of variables. it picks 
one to be a prototype for the aggregation. If the files differ, you will get 
different result. 

is that the problem? what were you expecting to happen? perhaps you are 
thinking of a "union" aggregation?
