I'm trying to hunt down an appropriate kriging package for my specific application, and I was hoping someone on the R list might have some pointers -- I'm interested in performing kriging and related spatial interpolations with one of the R packages, but I need to be able to provide my own point-to-point distances (e.g. I do not want to use standard between point distances, as calculated by Euclidean or other similar distance measures). Is there an R package that *I* can provide the matrix of distances between every pair of points (e.g. for 10 points, I would have a 10 x 10 matrix of distances)? Similarly, if this is possible, can I then provide this package a vector of distances from each point to an arbitrary unknown location (in my example, this would be a 1x10 vector) and apply the model to this vector to predict a single unknown point? It seems most (if not all) of the kriging packages I'm finding for R take the x,y,z location as the inputs and calculate these distances themselves. Thanks!
