Thank you Dominik, Vijay and Robers for all the valuable inputs.
Robert, the function you devised is really convenient. However, it fails when
the observed and modelled raster objects have different number of layers.
Please notice that the obs and model objects on the example from the qmap

Dear list,
I'm working on a local (nmax=100) space-time kriging model. I did a
cross-validation in which I made my model predict the values at 2000
randomly selected data points, based on the rest of the observations.
The results are quite good (the average error is very small, the errors are
