Random forest questions

I've been playing around with the RF implementation and I had a couple
questions:

- Does this RF implementation support weighted examples? (If so how do
I specify weights?)

- How do I get the RF score (confidence, probability, etc.) of a prediction?

Thanks!

No, the current implementation doesn't support weighted examples (yet ?), and you can't get the score for a prediction
