[R] Two questions about cloud().

[Rolf Turner]

(1) Is there a (simple) way of getting cloud() to do *both*
type="p" and type="h"?  I.e. of getting it to plot the points
as points *and* drop a perpendicular line to the underlying plane?

(2) Is there a way of telling cloud() to drop its lines to the
floor of the bounding box, rather than to the plane z=0?
I thought that the "zero.scaled" argument (for panel.3dscatter())
might be the ticket here, but when I pass this argument to cloud()
I get an error ``Error using packet 1 formal argument "zero.scaled"
matched by multiple actual arguments".

Ta.

	cheers,
