RSiteSearch("autologistic")

tells you what is known about this, which I'm afraid seems to be that no such function is available. Your question is very similar to the first hit in the site search, and that received no answer.

If you are willing to try a different framework, the ME() Moran eigenvector function in the spdep package is a possibility, albeit not yet well-proven. It adds selected eigenvectors from a centred spatial weights matrix to the RHS of the glm to "whiten out" spatial dependence, but it will also "whiten out" or paint over other spatially patterned mis-specification problems.
