[R] Contour plots of four two-dimensional matrices

[David Winsemius]

What is it that you want to do with these 4 plots? Overlay them with  
different color contours or plot them side-by-side on the same page?

?par  # for filled.contour but the implementation will be different  
for those two options.

  contourplot is is a lattice plotting function. See Figure 6.10 on  
Sarkar's Lattice book pages. levelplot is the closest analog to filled  
contour in lattice.
