I have put a Perl module 'DataFrame.pm' at GitHub.

Its very old version is used for my recommender system. (Thus k-means was implemented in this module.) This Perl module do not provide enough functions/methods for data mining, but we can do something with it.

• Please read README.md at first. It contains
  • How to use the module
  • Explanation of a test Perl script
• At your own risk.
• Your feedback is always welcome!

I will add functions, in particular the method which are marked as 'not yet' in the documentation. I will also implement some statistical learning algorithms.
