Re: Unofficial package

Unfortunately, this repo only contains source code for various frameworks (Weka, RapidMiner, R, etc), but no actual ready to use/install packages.

You could try compiling the Weka filter and add it to your classpath. With a bit of luck, the code is still compatible with Weka.

Cheers, Peter
