Great. I used the rgdal from CVS and that works fine.
The spgrass6 cvs has also been updated to guard against using an argument
to readOGR in rgdal not present in earlier versions.

Thanks, Bill

This is a pretty general question, and there are potentially many
ways to do it.
One way to get started would be to follow the example(s) in the help
page for the overlay() function in the sp package.

Adrian,
Thanks a lot for sharing your script. I was trying to write my own function
but your code
saved me a lot of time. It worked just fine. I just have one question. I
couldn't find
the function is.tess. Where is it?

I am trying to duplicate the example of T. Hengl given in his message of
2 Apr 2009 regarding "Running analysis on DEMs using GRASS (from R?)".
I have retrieved the latest CVS version (as of last night) of spgrass6
(v. 0.6-5). I am running on a 32-bit Intel Fedora 10 system.
Everything seem
Roger,
Here's the strange thing: it works! I assumed that the error on
install was fatal and nothing was built, but the bloody thing functions!
The 0.6-5 version I had before was built under 2.8.1, and following
your suggestion, I tried to install 0.6-5 in R 2.9.0 and it gave the
same err
On Linux i386 and x86_64, and Windows i386, everything looks OK.
I built 0.6-7 from source this morning on i386-apple-darwin8.11.1
without problem, linking to the Kyngesbury frameworks; it didn't fail
with that error.

I use rgdal for reading and
I have a list of made-up districts and corresponding zip codes. Based on
that I want to define my own polygons (for each district) and then use them
to create a map. Does anyone know how I would go about defining these?
thank you

Many thanks Virgilio for your initial suggestion and Roger for clarifications
and further suggestions.
Both SAR and SAM look attractive, and I'll give them a go. If any other
valuable information are gained on the way I'll post them under this thread.
Thanks again.

Dear Simon,
Perhaps you could model your data using a multivariate Normal with
spatial autocorrelation (using a SAR or CAR specification). In this way,
you can fix some of the values and then simulate the rest. You can tune
the autocorrelation c
The problem is that for universal kriging prediction, you need IDSaco
values at the prediction locations. So, you need to make the prediction
locations grid (newdata) a SpatialGridDataFrame that has these values on
each prediction location (grid node).
