 In reply to this post by Gram123 Just to give you a hint for the future: If you ask google for "odd, even, R" you get a messages from 2003 as second match: ------------------------------- Dave Caccace wrote: > Hi, > I'm trying to create a function, jim(p) which varies > depending on whether the value of p is odd or even.

My guess is, using so much capitals in your e-mail has turned away about 1000 helpful souls from your future posts. May be reading the posting guide and a one minute try to solve the problem by yourself googling would be appropriate? Think for a moment: Google would have given an answer (the answer!) in 1 minute. You wrote an e-mail to quite a few thousands of subscribers. That needed more than a minute on your side. And how many hours of reading time took it off of your readers?
