-----------------------------------------

Hi Ikumasa

> I attached new patch which has the additional modifications for DataLoader.parseString().

Cool, thanks.

> For DataConverter.convert(),
> my old patch has the modification, so no change is made on this.

Ah, I thought your last patch included all the modifications. So should I apply all three
patches one after another ?

> Yes, I have an own TreeBuilder and ResultAnalyzer for regression dataset.
> But I feel it is better that the patch for MAHOUT-840 doesn't have them.
> Is it good?

If you can add them to the patch as well that would be awesome !!!
