As always, 'str(rules)' will provide you with a view on the internal
structure of 'rules'. By the way, 'rules' is of class 'rules', see the
"rules-class" entry in the ARULES help pages, with more explanations on the
meaning of attributes.

For example, 'rules at quality' will show support, confidence, and lift of all
generated rules in sequence.
