OK. I can replicate this - there is still a bug in handling intercept-only models in lagsarlm() with method="SparseM"; it was partly fixed in January 2005. The equivalent model for errorsarlm() works: and the residuals are the same as for the lag model, as you can see. I'll try to fix the problem tomorrow. Thanks for a helpful report.
Thanks very much for your help. Using residuals(lagsarlm(Y ~ 1,method="eigen")) computes what I am looking for. Not sure why I was being so dense with respect to specifying an intercept-only model. One of those days.
The fix for the bug will be in the next release of spdep (0.3-23 or later) Roger
