I once used Gabor Grothendieck's trick using apply across an
array-redimmed matrix:

You would have convert XYZ table data to image list form, and it performs 
a resize, but it might be worth pursuing.

   Hello everyone,
   I was wondering if anyone knows how to smooth out a
contour-line plot. I am currently using the following
set of commands to create my plot

filled.contour(xx,yy, PP,
   color=cm.colors,
   plot.axes = {
     contour(xx, yy, P2,add=T, col="grey",drawlabels=FALSE)
     axis(1,1:length(xx),labels=tx)
     axis(2,1:length(yy),labels=ty)
    })

   The resulting plot looks OK but rather irregular,
with too many "sharp corners". Is there a way to
smooth the contour lines?

   Thank you so much
   Fernando
