Dear Professors. Bolker & Ripley:
Thank you both very much for all your creativity and hard work
both in your generall contributions to human knowledge and specifically
for helping make R the great thing it is today. I had not seen a reply
to that email in several days, so I made time to check it out. When I
replicated the error, I thought it my duty to report same. I know
that's more appropraite with "r-help" than with "r-devel", but I thought
such a comment might help someone. I certainly did NOT want to add to
someones' workload a requirement to reply to my comment.
Thanks again,
spencer graves
