thanks.
one more thing w/r this particular data set:
tri.mesh doesn't work in R but triangulation (S+SpatialStats) does work
interp.old (diff ncp) doesn't work in R but it does in Splus for the
same ncp values???
so,R or SPlus? who's right?

You have repeated (u,v) values in your data frame. It is not possible to
interpolate such data, and I get an error from 'interp' (not NAs).

There is no problem with interpolating from a regular grid, but be aware
that the triangul
Dear all;
First of all, this is probably a more conceptual question than a
R-related one, but still want to give it a try. When working with the
interpolation function "interp" from the package akima and the
triangulation function "tri.mesh" from package tripack I've got NA's
for the interpolation
