Panel Function for 3D Point Cloud

USAGE:

panel.cloud(x, y, subscripts, z, ...) 

ARGUMENTS:

x
x coordinates of points to be plotted.
y
y coordinates of points to be plotted.
subscripts
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.

SIDE EFFECTS:

A 3-D point cloud is drawn on the display.
