Display Decision Tree with a nice graphic

Post date: Dec 30, 2014 8:59:18 AM

If you are using decision tree classifier in R, instead of boring text output, you might want to visualize the final tree (learned tree) in some nice graphic. Today I learn that we can display a decision tree in an awesome way by just installing these packages:

• rattle
• rpart.plot

The display is just great and worth the 3-minute installation time.

I also found these tutorials extremely helpful about how to display decision tree:
