title: Balanced Random Forest in R
body: <p>I was wondering if there is a implementation of Balanced Random Forests (<a href="http://statistics.berkeley.edu/sites/default/files/tech-reports/666.pdf" rel="nofollow noreferrer">http://statistics.berkeley.edu/sites/default/files/tech-reports/666.pdf</a>) in R. They are useful for problems with imbalanced classes. I was also wondering if it is analogous to using the <code>sampsize</code> parameter for <code>randomForest()</code> in <code>randomForest</code>. From what I can tell, there isn't a direct implementation of Balanced Random Forests, but that could be that it is exactly what <code>sampsize</code> does.</p>
