[R] 3d contours

[Spencer Graves]

Have you cosidered (a) "contour" or (b) "image" possibly followed by 
"contour(..., add=TRUE)", possibly preceeded by "interp"?  If you have, 
then you must want to plot contours in three dimensions where a fourth 
is constant ... ? 

hope this helps.  spencer graves
