Panel Function for Wireframe Surface

USAGE:

panel.wireframe(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 polygon. By default, the trellis parameter list wires will be used to control line width ( lwd ), line type ( lty ) and color ( col ) for the wireframe lines; the regions parameters will be used to control color ( col ) of the surface patches in color draping. Panel color is 0 (for background) by default, to cause near surface patches to obscure ones plotted earlier. The panel function takes care to plot patches in order, from most distant to nearest the eyepoint.

SIDE EFFECTS:

A wireframe surface is drawn on the display.
