Instances and ARFF file dataset manipulations

[kostasdizas]

Hi
looking at the WEKA source code I found a number of additional implemented features that allow for dataset manipulations. Can that work in python too, or is it missing intentionally? Is there a plan to include support for this in the wrapper?

Some examples can be found in the docs below:

• http://weka.sourceforge.net/doc.dev/weka/core/Instances.html#main(java.lang.String[])
• http://weka.sourceforge.net/doc.dev/weka/core/Instances.html#mergeInstances(weka.core.Instances,%20weka.core.Instances)

This project is something I only work on only when I get around to in
my spare time, sort of a fun project on the side. So far, I didn't see
any need in implementing this functionality. However, please open a
feature request issue on github and I'll add it when I get around to.

Cheers, Peter
