Edzer,
Not to deflate Cesar's project, but from our past email exchanges you
are aware that I have been very pleased with the standalone version of
your gstat program and feel that it interfaces wonderfully with GRASS
6.x; I would highly recommend this approach to anyone. Also, for those

Dear Cesar,
Krige, idw of predict.gstat all return objects with the prediction. You only
get maps when you plot these objects. So you only need to find out how to
return these objects with JRI to your GIS.
Edzer Pebesma will be best positioned to answer your question about gstat's
capability o
Hello list,
we are trying to implement spatial interpolations (IDW and several types
of Kriging) in our open source GIS application, which is written in Java.
We plan to use JRI to connect with R from Java, and then use the
features of "gstat" R-package to calculate the interpolations.

No, only rectangular windows are permitted. You could try a large

Dear all,
I have a question regarding the spdep package. I want to produce
directional (anisotropic) correlograms. Is there any way to generate
these with spdep?
I am analyzing aerial photographs of patterned ecosystems, in which the
patterns are often directional.
Thanks in advance,
