R help - Mar 2004 - Ordinal logistic regression using spatial data

I have a spatial data set with ordinal response variable containing 
four levels. I would like to know if and how spatial autocorrelation 
can be taken into account when ordinal logistic regression is used 
(e.g. the function lrm from the Design package).

Thanks for your help!

lrm (through the robcov and bootcov functions) can take into account
general intra-cluster correlations.  This works best when clusters do not
contain very many observations.  Different clusters are assumed to be
independent.
