I have matrix (n x3) that represents discrete data. 
Each row of matrix is 3-D point (x,y,z). I would like 
to get contour map (z value) at two dimension 
(x,y). How can I use related contour function to do 
this job?

clines package some time ago. I will mail you (LZ) a copy

(Paul, I assume this is ok?).
