[R-sig-Geo] heteroskedasticity corrections for lagsarlm() in spdep

[Christian A.Oberst]

I tested the procedure from Marco and it worked fine under the recent spdep 
update (05-40). 

But are there any heteroskedastic corrections for the other spatial models 
(Spatial lag, SAC or Spatial Durbin) estimated with ML-estimations (lagsarlm, 
errorsarlm, sacsarlm)? I know that there is the sphet package (use sphet_1.1-0), 
but in this are as far as I see only GMM procedures included.

I am grateful for any suggestions
