[sage-support] Turning axes off

2010-07-12 Thread Alec Battles
I am using SAGE, not so much as a mathematical tool, but to make art. With that in mind, I want to disable axes pretty much permanently. I am currently plotting complex functions such as sage: f(z) = z^5 + z - 1 + 1/z sage: complex_plot(f, (-3, 3), (-3, 3)) Thanks, Alec -- To post to this grou

[sage-support] How to use R's untar in Sage?

2010-07-12 Thread rickhg12hs
I've tried to use R's untar command a number of different ways from Sage's commandline interface and I am having trouble listing the contents of a LZMA compressed TAR file. Actually, I don't seem to get any desirable output from r.untar so I am thinking I'm not even close to using the correct synta
