For this purpose, I like Fernando's data array:
http://github.com/fperez/datarray
A very simple subclass of ndarrays that answers my most-wanted feature in
terms of richer data structures.

But, on the other hand, I have never really used R's advanced features,
so I may be missing something.

My 2 cents,
