Hi Maria,

You need first take a good look at the spdep package documentation (here
<http://cran.r-project.org/web/packages/spdep/index.html>and
here<http://cran.r-project.org/web/packages/spdep/spdep.pdf>),
 and some good tutorials maded by the CISS <http://www.csiss.org/>, like this
one <http://geodacenter.asu.edu/system/files/rex1.pdf>. Also, I recommed the
Roger Bivand's book Applied Spatial
Analysis<http://www.springer.com/public+health/epidemiology/book/978-0-387-78170-9>
.
