example(GMerrorsar)
?GMerrorsar # examples at end

but note that this function is *not* for fitting spatial logit models, for 
which no functions are available in R. It is for fitting spatial error 
models with a continuous dependent variable, and may be used as an 
alternative to maximum likelihood.

Had you shown the code you were using for this function, it would have 
been easier to see what you are doing wrong.

Hope this helps,
