title: Visualizing trees of the final model in Caret
body: <p>Is it possible to visualize trees in Caret final model trained by random forest?</p>
  
  <pre><code> train_control &lt;- trainControl(method="cv", number=5,savePredictions =  TRUE,classProbs = TRUE)
   output &lt;- train(Species~., data=iris, trControl=train_control, method="rf")
  </code></pre>
  
  <p>I would like to know depth of the trees and visualize some trees of the final model, I found out that there's <code>output$finalModel$forest</code> for the output but I don't know how to use it for plots.</p>
