Panel Function for Contour Plots and Level Plots

USAGE:

panel.contourplot(x, y, z, subscripts, ...)
panel.levelplot(x, y, z, subscripts, ...)

ARGUMENTS:

x
x coordinates of points to be plotted.
y
y coordinates of points to be plotted.
z
z coordinates of all points. z[subscripts] gives the sets of z values corresponding to x and y.
subscripts
a vector of subscripts, that tells where in the overall data, the selected x and y observations originate.
...
graphical parameters that are passed to lines. By default, the trellis parameter list add.line will be used to control line width ( lwd), line type ( lty), and color ( col) for the contour lines. By default, the add.text parameters will be used to control character expansion ( cex), color ( col), and font for contour line labels.

SIDE EFFECTS:

A contour plot or levelplot is drawn on the display.
