Subject: Rules for coding expanded formulas
I'm reading Section 2.4.1 Rules for Coding Expanded Formulas in
Statistical Models in S by Chambers and Hastie. It is a little
abstract for me. Could somebody point me some references that have
more examples and more explanations that can help me understand the
rules (in particular, the ones on page 39 and 40)?
