title: How to specify split in a decision tree in R programming?
body: <p>I am trying to apply decision tree here. Decision tree takes care of splitting at each node itself. But at first node I want to split my tree on the basis of "Age". How do I force that.?</p>
  
  <pre><code>library(party)    
  fit2 &lt;- ctree(Churn ~ Gender + Age + LastTransaction + Payment.Method + spend + marStat, data = tsdata)
  </code></pre>
