Maybe I just don't really understand what you are after. The elements
of a data.frame are vectors so by definition they only have one
dimension. Furthermore, they are required to be the same length -
otherwise it wouldn't be a proper data.frame, anymore.

So I guess you really want to accomplish something I didn't quite
grasp. Could you give an example?
