It sounds very well suited for Linux or MacOSX, but I've little idea about the GRASS+R Windows situation. Maybe someone on the statsgrass mailing list knows?

You could try python. The next version of GRASS will use python heavily for the GUI, so expect lots of example scripts, help on the mailing list from fellow travelers, and tight integration with the code. Learn python in 10 min: http://www.poromenos.org/tutorials/python Also there is a SWIG/Python interface to any needed GIS library functions, which is pretty cool, although the grass modules generally give you what you need without having to resort to using any low-level libgis functions. see http://grass.gdf-hannover.de/wiki/GRASS_and_Python http://freegis.org/cgi-bin/viewcvs.cgi/grass6/swig/python/ Hamish ____________________________________________________________________________________ Luggage?
