Hi,

I am using the Random Forest package to classify observations into one of two classes. My data is unbalanced with the minority class accounting for 7% of total data set.

I have heard the 10-Fold Cross validation can help me with improving classification. But being new at most of this it's not something I can do from scratch on my own. So I have spent all this morning trying to find a good example script of 10-Fold Cross-validation and RandomForest where the ratio of classes is maintained. I have done multiple google searches. The only thing I came across was the ipred package and errorest. But when I was going through the?errorest examples I did not see examples of actual classification output only error rates.  So I turn to you guys. Do you have a script I can refer to and learn off of to accomplish what I need to accomplish?

Dan
