R help - May 2010 - randomForest: sampling with replacement?

Hello!

I know that as trees are constructed, the root node contains a
bootstrap sample of data of the same size as original the data set.
Would you please confirm that it is a bootstrap sample with replacement?
I think it is - just wanted to make sure.
Thank you very much!

See the "replace" argument in ?randomForest.
