Hi:

It's a little hard to help on that front without a reproducible example but
you could read the help page of plot.lda in the MASS package, where you
would find that it takes both xlab and ylab arguments, and for which you can
probably pass main as well since it contains a ... argument. Did you try it?

If you want to change group names, it's generally easier to make the change
in the data (add a new variable with modified values) and use that in the
model call.

HTH,
Dennis
