[R-sig-Geo] Mean Effects SAR Model

It means exactly what you say below:

If I specify the model syntax lagsarlm(Y ~ 1, ...) I get:

Spatial lag model
Jacobian calculated using sparse matrix techniques using SparseM
Error: subscript out of bounds

Any idea what subscript the program is talking about?
