Please give a reproducible example [1] showing what you are doing, 
preferably with a built-in data set. In any case, an lm object made from a 
sarlm object will fix the spatial coefficient and loose its uncertainty.


Can you use an model class accepted in piecewiseSEM that fits an MRF 
random effect?
