[R] regarding 3d Bar Plot --- correction.

I mis-spoke.  It seems I had two collections of functions in the same
directory.  One by Colin Goodall, and one by David Scott (I have no
record of where he is/was located).  It is the *latter* collection
that does all its work from within Fortran.

I'll have another look at what Colin Goodall actually wrote to see if
it could be useful to guarav.
