: (Lattice): Overlaying more than one trend surface using contourplot() and wireframe()
Hi,
Is there a way to plot more than one trend surface using the functions
contourplot() and wireframe(). I have found an add=T in contour(), but

I have taken the example 11-2 (pages 441-451) from Design and analysis
