David:
I privately suggested he post to manipulatr because Hadley is more
likely to see his question there first than in R-help. He originally
posted here, noted the cross-posting and referral at manipulatr and
responded back to this list when he got a successful reply from
Hadley. I don't see that he's done anything wrong; in fact, he's been
exceptionally polite. If you want to yell at anybody, yell at me.
