Folks: I am getting duplicate messages on posts. Please correct my details if I'm wrong, but I believe it's because folks are posting to **both** the addresses, r-help@r-project.org and r-h...@stat.math.eth.ch . I believe the first is just an alias for the second, and that's why the suplicate posts occur. So please choose one or the other, not both.
