[R-sig-Geo] extract values from errorsarlm/lagsarlm

[Steve Hong]

Dear List,

I would like to extract values from outputs of errorsarlm and lagsarlm. For example (below), I need coefficient estimate, Std.Error, z value, p-value of coefficients, LL, and AIC etc. I tried "summary(ra7.eslm1)$coeff", it gives only coefficient estimates (not Std.Error, z-value, and p-value). Is there any easy way to extract those values and AIC and LL?

Thank you!

Steve Hong
