develop weighted Random Forest "R" package

Cancelled

Job Description

We're going to use "weighted" Random Forest algorithm for imbalanced data,
because usual Random Forest algorithm doesn't work for them.

We're using "R" to analyze those data.
in our labeled data,there is four classification,and the each volume is imbalanced.

The problem is that there is no "weighted" Random Forest package in R.
Only there is usual Random Forest package.

So developing weighted Random Forest package is the goal of this job.

we found some papers contain the algorithm of weighted Random Forest.
