[R] Random Forest & Cross Validation

[ronzhao]

Thanks, Max.

Yes, I　did some feature selections in the training set. Basically, I
selected the top 1000 SNPs based on OOB error and grow the forest using
training set, then using the test set to validate the forest grown.

But if I do the same thing in test set, the top SNPs would be different than
those in training set. That may be difficult to interpret.
