An extension of the Rpackage geoR that works with cost-based distances
Basically, three functions are adapted in order to admit custom distance matrices as additional arguments.
Namely variog, to produce empirical variograms; likfit, to fit theoretical variograms and krige.conv, to preform kriging.
Check the documentation on these functions for examples of usage.
The cost-based distance matrix need to be computed elsewhere.
I have used GRASS GIS, with the help of a script.
However, currently there is an R-package gdistance which could help in computing cost-based distances.
