Condition to factor (easy to remember)
Dear List,
creating factors in a given non-default orders is notoriously difficult to
explain in a course. Students love the ifelse construct given below most,
but I remember some comment from Martin M?chler (?) that ifelse should be
banned from courses.
Any better idea? Not necessarily short, easy to remember is important.
