23 There are oodles of scientific interfaces to Python. I'm guessing there
24 is at least one that will do this. I'm not a Pythonista, however, I'm a
25 Rubyist, so I can't give you any names, or tell you whether what you
26 want to do is in Portage or not. One you might want to check is Sage
27 ( Another is StatPy
28 (
30 However, this is a very common mode of interaction in exploratory data
31 analysis, and just about every statistics package out there can do this.
32 xlisp-stat used to be in Portage, but it's in Lisp. And R is in Portage
33 for sure and is what *I* use to do this sort of thing. If you don't mind
34 learning another language, I'd recommend R.
36 There is supposedly an R-Python interface available, but since I don't
37 know Python, I've never bothered to check it out. If you want to go this
38 way, do a Google search for "RSPython".
