Hi,
I'm using the Tps function of the fields package to plot 2D surfaces. My
problem is that some arrays have a lot of zeroes and this function fits the
data in a way that contour lines for zero are all over the place. Sometimes
there are lines where there shouldn't be any that extend from the part of
the array where there are values greater than zero. How can't I get rid of
them (besides using Illustrator or photoshop)? I have tried changing the
lambda, but it doesn't help. Is there any other function that would work
better to smooth data?
thank you in advance,
Tania
