Thank you for the pointer to your paper "Getting Started with Lattice
Graphics" -- it looks very useful.
I think we're talking past each other on the question of the semantics
of formula operators, and it's probably not productive to continue. I
would guess that the underlying issue is that we co

Deepayan,
Thanks again for your explanations. I must admit I am still
struggling with some of these concepts (though I have in fact read
more than just help pages!), and I would be delighted to find a

Given a data frame of a categorical variable and two continuous
variables, I would like to display one continuous variable against the
other for each value of the categorical variable, all superimposed on
the same plot. For example:
data(Indometh); str(Indometh)
