Subject: Single factor from interaction.
I have a vague recollection of seeing reference, fairly recently, to
a function that forms a single factor which ``codes'' the interaction
between two (or more?) factors. Do I recollect correctly? It would
be easy enough to roll one's own, but if there is an existing
function it probably does a much cleverer job than I would do.
cheers,
