classification of data

[Moritz Lennert]

Hello !

I'm looking for a (statistical) program that helps classifying data into
intervals for use in thematical maps, i.e. I would like to be able to give
an input data file, tell the program how many class intevals and which
classification algorithm (equal distance, standard deviation, discontinuities, etc...) I
want and then get an output with the class ranges.

Soemone suggested r.reclass, but if I understand this module it only
reclassifies maps according to class intervals you already know.

Does anybody know of such a program ? I could try and write one myself,
but if it already exists why do the work again ? ;-)
