I find it hard to believe they wrote it all in IDL! I'm guessing its probably scriptable in IDL, but underneath its written in something else... I could be wrong though! > To my oppinion, R language is superior, compared to IDL, in all aspects. > However, ENVI is the rather convenient and feature rich tool. I clicked on 'Product Documentation' on the ENVI site and it wanted me to log in or create a new user. To see the documentation? To find out what the program is about? Oh, what I really wanted was the Feature Tour.. > Is anyone aware about any work, dedicated to the creation of > something, similar to the ENVI, but in R? Last year I looked at GIS-R linkages, with the added criteria of being open source and cross-platform. There are now a few free GIS packages that can do this kind of thing, with a little added glue. I settled on OpenEV - it has vector and raster support, its extensible in Python and uses Gtk for dialogs which you can customise. All I needed was to get Python talking to R, so I wrote some Python bindings to Rserve. Now I've got a GIS with a menu that drops down, you choose the point layers you want to work on, click 'Go', and R does some analysis that ends up as a raster layer back in the GIS. The user doesnt care that R did it. Other GIS solutions are available!
