[R] Bayesian Block Kriging?

Hi Candan,

As a more general remark, there is a mailing list for spatial data, 
including interpolation, r-sig-geo. This question would be more 
appropriate there. I gave some answers in-line below from what I could 
come up with. Reposting on r-sig-geo would be  a good idea to get more 
response.

cheers,
Paul

possibly, I've never used krige.bayes

to my knowledge, no

write a new function that combines both things you want (you question is 
a bit vague)
