image classification in R
This may be a stupid question but has anyone tried the unsupervised option in Random Forest for unsupervised image classification? I'm not sure how that would work. Ned

Dear list, I want to do some unsupervised image classification of some landsat imagery, I think I can read in the multi-band rasters using rgdal, but has anyone tried doing this in R? I am thinking (after looking at documentation for how GRASS and ArcGIS do it) that I need to do an initial hierarchical clustering to define clusters, but does anyone have an idea on how to do a maximum likelihood classification of the imagery? Would a discriminant function approach work? Any advice anyone may have would be greatly appreciated, and i'm very sorry but I don't have a working example yet.
