• R or Python for file manipulation

  - by danspants

  I have 4 reasonably complex r scripts that are used to manipulate csv and xml files. These were created by another department where they work exclusively in r. My understanding is that while r is very fast when dealing with data, it's not really optimised for file manipulation. Can I expect to get significant speed increases by converting these scripts to python? Or is this something of a waste of time?

• Financial Charts / Graphs in Ruby or Python

  - by Eric the Red

  What are my best options for creating a financial open-high-low-close (OHLC) chart in a high level language like Ruby or Python? While there seem to be a lot of options for graphing, I haven't seen any gems or eggs with this kind of chart. http://en.wikipedia.org/wiki/Open-high-low-close_chart (but I don't need the moving average or Bollinger bands) JFreeChart can do this in Java, but I'd like to make my codebase as small and simple as possible. Thanks!

• Installing Python egg dependencies without apt-get

  - by l0b0

  I've got a Python module which is distributed on PyPI, and therefore installable using easy_install. It depends on lxml, which in turn depends on libxslt1-dev. I'm unable to install libxslt1-dev with easy_install, so it doesn't work to put it in install_requires. Is there any way I can get setuptools to install it instead of resorting to apt-get?
