There are a couple of issues here. panel.wireframe() has a very 
different argument list in S-PLUS and lattice, and even though the ones 
you have used are common to both, the sequence is different. Using 
named arguments should fix this, i.e., use 

        panel = function(x, y, subscripts, z, angle, ...)
          w <- unique(angle[subscripts])
-         panel.wireframe(x, y, subscripts, z,
+         panel.wireframe(x = x, y = y, subscripts = subscripts, z = z,
                          screen = list(z = w, x = -60, y = 0), ...)

This will give you non-empty panels, but not different angles of 
rotation. This is because panel.wireframe doesn't handle screen, the 
top-level function (wireframe) does. There's no good reason for this 
behavior, so I'll fix it. But since this would be an API change, I 
don't think I should do it in a stable update. I can send you a patched 
version privately if you wish.
