Hi,
I'd like to
(1) plot a perspective view of a 3D scatterplot, with a fitted
(curved)
surface;
(2) have a "stick" from each point vertically to the surface.
The latter helps one visualize where a point lies in 3D, relative
to the
surface. Is there a variant of the cloud function (lattice
package) which
might do this? As far as I can tell, the cloud function will
(essentially)
only plot the a stick from a point to z=0, rather than to the surface.
Perhaps the scatterplot3d package is what you're looking for.
cheers,
Rolf Turner
