Ah, you are right. I misread the interpp help and thought it only
output a regular grid. That will do the trick. Thanks.

Tps() is great -- I've been using it. I suppose I could use it for
this problem too by setting the curvature penalty to zero (forcing it
to interpolate). The interpp a la Miha suggestion I think will be
better for what I want.

What about interpp in akima package that does pointwise bivariate interpolation
for irregular data? Was that what you wanted?
All best

Anyone know of code that will do bilinear interpolation from irregular
samples to another set of irregular locations (including points
possibly outside the convex hull of the original points)? Akima
interpolates to a regular grid AFAICT. I did find one package on CRAN
that does this will splines, b
Thomas,
I have seen this error from package gstat before but find it hard to
guess what caused it without looking over your shoulder. Please send the
script that led to the error.

Hi there
I have problems using krige(). I want to do ordinary kriging, but always
have the problem of "dimensions do not match: locations 1956 and data 141".
Dim(mygrid) returns NULL. Is that supposed to be? I guess not, therefore I
must have made mistakes making my grid -> I want to use an ESRI s
Hello,
I'm interested in the origin of the idea behind sp's SpatialPixels.
What other software/s implement this concept, of storing a sparse grid
of pixels?
I'm aware of the SparseMatrix in R, and I haven't explored that thread -
are there specifically GIS implementations of this idea?
Cheers,
