Alex, there are a couple of books that would be worth buying:

Bivand, Roger S., Edzer J. Pebesma, and Virgilio Gómez-Rubio. 2008. 
Applied Spatial Data Analysis with R. 1st ed. Springer.

Neteler, Markus, and Helena Mitasova. 2007. Open Source GIS: A GRASS GIS 
Approach. 3rd ed. Springer.


best,
Anthon
