title: How to save a data.tree in R?
body: <p>I have been looking over the manual of the <code>data.tree</code> package, however I was not able to find a way to save a <code>data.tree</code> structure once you created one. Is there a way to write a data.tree structure instead of transforming it to another structure(i.e. data.frame) and then saving it?</p>
