[R-sig-Geo] SpatialPoints, SpatialGrid and related terminology

[Giuseppe Calamita]

Ciao Gabriele,
you can find a shorter yet very useful descriptions of how spatial classes
work in one of the vignettes of the sp-package.

To visualize that, simply write on R terminal 
> vignette("intro_sp") 
this will open a pdf. 
You can also download it directly from
http://cran.r-project.org/web/packages/sp/vignettes/intro_sp.pdf

If you use 
> vignette(package= "sp") 
you'll see all the available vignette in that package, whereas if you use 
> vignette()
you'll see ALL the available vignette in all the installed package (this may
take a long time).

Hope this helps
Giuseppe
