title: Save a random Forest object
body: <p>I have a randomForest object that I want to save for later use.  I've tried some of the following but with no luck.</p>
  
  <pre><code>save(topDawg , file="myRFobject.RData")
  </code></pre>
  
  <p>This just saves a string "topDawg"</p>
  
  <pre><code>&gt; formula(topDawg)
  Error in formula.default(topDawg) : invalid formula
  
  
  &gt; save(getTree(topDawg))
  Error in save(getTree(topDawg)) : object ‘getTree(topDawg)’ not found
  </code></pre>
  
  <p>Any suggestions?</p>
