The strength and correlation among trees in a random forest are based on
the predictions of the individual trees. You can get that from the
predict() method for a randomForest object with the predict.all option.
>From there you can compute the strengths and correlations on your own.

Forest in R package " randomForest"?
Hello!
I want to estimate strength and correlation of RandomForest, but
in package "randomForest" there is not an interface to get it. I think I
must to change the source code
