[R-sig-Geo] R squared in lagsarlm

What do you mean by: "what parameters of SAR we should expose"? What do 
you mean by SAR? Do you mean the SAR model (simultaneous autoregressive 
model, a.k.a. the simultaneous spatial error model) or the SAR model 
(spatial autoregressive model a.k.a. the simultaneous spatial lag model)? 
If the spatial lag model, only ever report impacts, never report the 
betas. Please be more precise.
