This function also takes 3D arguments listed under
trellis.3d.args.
ARGUMENTS:
formula
formula defining the 3-D surface and the grid over which the surface is
defined. This is a formula of the form:
z ~ x * y | g1 * g2 * ... x,
y , and
z are numeric vectors determine the 3-D space position of
the points in the point-cloud display. Any 3-D points containing NAs will
be removed.
The given variables
g1,
g2 ,
... may be omitted.
VALUE:
