Hi,

You could use the list of neighbors, for example given by spdep::poly2nb
(but there are other nb objects relationships: knearneigh and dnearneigh),
then use mean() function

Also, you could use spatial lagging using spdep::lag.listw, but before, look
after the spatial lag formula if it fits your need.

Hope it will help you,

Mathieu
