Sources for learning mapping/GIS with R?

There's a spatial taskview that's the perfect place to start:
installing the taskview will
give you very nearly all the related packages.

http://cran.r-project.org/web/views/Spatial.html

For learning how to use them, Bivand et al's Spatial Analysis book is good:

Can anyone recommend some basic resources for learning how to create maps
with R?
Or recommend packages that are particularly helpful?

Thanks!
