Subject: Smoothing z-values according to their x, y positions
Dear All,
I'm sure this is not the first time this question comes up but I
couldn't find the keywords that would point me out to it - so
apologies if this is a re-post.
Basically I've got thousands of points, each depending on three variables:
x, y, and z.
if I do a plot(x,y, col=z), I get something very messy.
So I would like to smooth the values of z according to the values of
their neighbors (given by x and y).
Could you please point me out to the function(s) I should look into
for the smothing, and
possibly for the plotting?
Many thanks for your help,
Emmanuel
