How to do it...

Perform the following steps to visualize the conditional inference tree:

1. Use the plot function to plot ctree.model built in the last recipe:

        > plot(ctree.model)  

A conditional inference tree of churn data

2. To obtain a simple conditional inference tree, one can reduce the built model with less input features and redraw the classification tree:

        > daycharge.model = ctree(churn ~ total_day_charge, data         = trainset)
        > plot(daycharge.model)  

A conditional inference tree using the total_day_charge variable as only a split condition ...
