Well, it could be that I am missing something important in what you are 
trying to do, but you might want to look at it (tfpersp in tframePlus). 
It certainly allows you to pass your own labels, and most of the other 
arguments to persp. It just tries to make default guesses that work for 
time series, and provide windowing.
