Hi, The discussion there makes me wonder if we should include Raspberry Pi binaries for Sage at sagemath.org? There's [1], but something official might be better. Any thoughts? [1] http://www.raspberrypi.org/phpBB3/viewtopic.php?t=46721&p=367445 On Thu, Nov 21, 2013 at 6:22 PM, William Stein

I would be in favor of keeping R, it is basically the only thing that we have for statistics. This is different from Octave, say---anything that you could do with Octave you can basically do with Sage, but there is very little that we currently can do to replace R functionality. Having said tha
