title: How to pick a different model from the `finalModel` in caret?
body: <p>In <code>caret</code>, using functions <code>best</code>, <code>tolerance</code>, etc. I can pick a less complex model with a small performance penalty (<a href="http://topepo.github.io/caret/model-training-and-tuning.html#choosing-the-final-model" rel="nofollow noreferrer">tutorial</a>).</p>
  
  <p>After using <code>tolerance</code>, I now know that I want, say, the 3rd models among all the ones tuned by <code>caret</code>. Is it possible to extract that model similar to how I can pick <code>caret_result$finalModel</code>? Or do I have to take the hyperparameters of that model and re-fit the model with them?</p>
