Yes, it does :-)! Thanks a lot.

Sure, actually I used "na.rm=T" -- but not "TRUE". My alleged
knowledge about this is based on a book about S and S-Plus.
I'm still waiting for "An Introductory in R" as I wrote in a
mail some days ago. I can not read Docus on a monitor, I need
paper in my hand =).

Best regards,

Christoph
