[R] plot points using vis.gam

[Simon Wood]

There is no easy way to do this. It might be possible to customize vis.gam, to 
be able to do this by using the same trick that allows you to add elements to 
a 3D plot with `persp' (see help file for persp), but it would be quite a bit 
of coding, I guess.
