a vector of subscripts, that tells where in the overall data, the
selected
x and
y observations originate.
z
z coordinates of all points.
z[subscripts] gives the sets of
z values corresponding to
x and
y.
...
graphical parameters that are passed to
points or
lines.
By default, the trellis
parameter list
cloud.3d will be used to control
character size (
cex ), plotting symbol (
pch ), font, and color (
col ) for
points; and line width (
lwd ), line type (
lty ), and color (
col ) for
crosses.
If the plotting character parameter,
pch, is a plus (
+ ), the symbol
drawn is actually a 3-D cross.
