Hi,

These are the list of weights.

They can be defined automatically with these different types:
W, B, C, U, and S

See http://rss.acs.unt.edu/Rdoc/library/spdep/html/nb2listw.html
or asdar book

Weights can also be different given the length of boundaries shared between
tracts.
see vect2neigh
http://cran.r-project.org/web/packages/spdep/vignettes/CO69.pdf

They can be specified manually or automatically given order criterias.

Best,

Mathieu
