[R] LDA newbie question

I have tried the (MASS) LDA example (Iris) that's given on the help
pages but I don't fully understand the results. Perhaps someone could be
so kind to explain it to me.
On the help pages it says as return values:
What I get as results are
coefficients of linear discriminants
proportion of trace
OK, so the first 3 appear to be the same in both cases (perhaps just a
different wording) and I know I can show the other return values by
something like z$call. No problem.
But what is the proportion of trace?
Is there a simple way to get the discriminant score or do I have to
manually multiply the coefficients with the data?
