title: Partition using rpart.plot
body: <p>I am implementing a decision tree but when building the graph with <code>rpart.plot</code> it gets huge, making it impossible to see. Is there a way to subdivide when generating the plot;</p>
  
  <pre><code>rpart.plot (tree, type = 3, fallen = T,leaf.round = 1, extra = 100,
              branch = .1, box.palette = "RdBu")
  </code></pre>
