datamash program

[Rasmussen, Lloyd]

R definitely runs locally.  Jonathan Godfrey, a blind professor of statistics in New Zealand, uses and promotes R a great deal. Not sure if he is running it on Linux or on Windows, but probably either one. He is a frequent contributor to the BlindMath listserv on NFBNet.org .

run locally or required an internet server to use.  I like to be able to run stuff locally since we have unreliable internet in my area of America and actually most of America has to live with unreliable internet since lots of it is rural and in underserved areas.
