Simple answer: use R. I fought with Python+NumPy+SciPy+Matplotlib
problems for years before I discovered R. Night and day change. One
package that just works. Thousands of libraries that just work.
Developers, I'm not denigrating your efforts. I like Python, and I
really tried to make Python+NumPy+SciPy+Matplotlib my main tool for
years, but as a mere user it was simply too difficult to maintain the
parts -- every hour spent screwing with tool problems is an hour lost
to creative work.
Perhaps the NumPy+SciPy+Matplotlib community could learn something by
looking at how the R community works? To this mere user who wants to
get a job done, it's a night and day difference. I still use Python
for GP programming, but there's a snowball's chance I'd ever use
anything but R for my main interest, which is econometrics.
