Hi Thierry, thank yo for the reply.
I did find that post by Edzer also, but thought that perhaps someone may have done something since. If I remember, Edzer's reply post was from 2007. I should have maybe mentioned that on my post. So, it appears that FK has not been implemented in R. i wonder why...? If I understand correctly, it should not be too difficult to do if you already have the kriging algorithm. It seems that one just sets the constraint on the kriging weights to 0 rather than 1. Does this sound right?
