I agree with this, that was my point in my original reply.  Apply is 
*not* passing 2 arguments simply because you are selecting two columns 
of the input object, it's passing *one argument*, which is the *entire 
row* of the input object.  You can then access them individually within 
the stats function, as Henrique shows.
