Hi Nick,

The Raster package has been my key to working with images in R. 
Leveraging the Raster package you can use just about any classification 
engine or statistics queries you want. I've been quite impress with the 
RandomForest package (among others) for image classification. I'm happy 
to share the script I use and a guide with instructions if you're 

All the best,
