Dear list,

I'm into the process of learning R's geospatial framework. Currently I'm
studying scripts that perform a kriging operation on heavy metal
measurements on a EU scale, see this link:

http://eusoils.jrc.ec.europa.eu/foregshmc/

Now, I would like to derive averages of the fitted model surface for the EU
member countries. So: take the intersection of the country boundaries and
the interpolated surface, and derive an average value for that.
Could someone provide me with some pointers to get started? What R lib would
be suited for this?

Thanks a bunch,
Frans
