Eberhard,
> My malpractice insurance gives me a discount if I consult up to 22 > hours per week in a 3 months period. i wonder if you might add up the number of hours worked over the (92 (?)) days of November, December, January, divide by that number of days, then divide by seven? that would be, obviously, a bit of an approximation. but, it's not clear exactly how exact the insurance company wants. cheers, Greg ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
