confint() for difference of effect levels [R for BE/BA]

Hi all,

let us say we have an lm object for a BE analysis in a study where we have n treatments.
Is there a way to use confint() to derive CI's for the difference of the i'th and j'th treatments (where obviously i!=j, and i is within 1..n and j is within 1..n) ?

If not, is there another built-in function that achieves this goal?

Google isn't my friend.:-):-)
Many thanks.

I could be wrong, but...
Best regards,
ElMaestro
