[R-sig-Geo] Raster Sample Data

[Michele Tobias]

I'm looking for some raster data to use to with the Raster package (it's 
for students to work with in a class) and I was wondering if anyone had 
some suggestions of any sample datasets that come with other R 
packages.  I've found the Meuse.grid data that comes with the SP Package 
which is a good start, but I'd also like to find some other data.  
Vegetation reflectance data would be ideal so we can do some NDVI 
calculations, but anything we can logically run some mathematical 
operations on would work.  It would also be good if the files were of a 
relatively small size.  Downloading full Landsat scenes, for example, 
will be pretty cumbersome.

Thanks for your help!

best,
Michele
