good resource for decision trees parameter selection?

A very good reference on how to set various parameters of different models in RapidMiner - including Decision Trees - is the book by Vijay Kotu and Bala Deshpande, Data Science: Concepts and Practice, Second Edition, Morgan Kaufmann Pubs. See section 4.1 on Decision Trees. An important aspect of reading a chapter like this is that it will explain not only what each parameter does but also how the algorithm building the tree is using these parameters.
