R help - Mar 2009 - spatial markov chain methods

Hello,

can any one point me to R-packages (if available) which include spatial 
Markov Chain methods?
My second question is more general but hopefully not OT: Currently we 
are using the software TPROGS, which let people simulate property 
distributions in space by some Markov Chain approaches. We face some 
problems due to the lack of information between distances of samples 
along borehole path and among boreholes. Is there any way to "trick"
it
like for instants in variogram modeling were one might use nested 
variograms...?

Thank you, Torsten

The spatstat package has facilities for simulating (non-Poisson) spatial
point processes vi MCMC (Metropolis-Hastings) methods.  But it's  
probably
not point patterns that you're after.
