[R] New var

[Jeff Newmiller]

You do understand that this is not the "do my work for me" mailing list, don't you? You should be asking questions like "why doesn't my code do one of these if conditions?" so that you know HOW to write the rest of them yourself. 

In addition you have been posting here long enough to know that your use of HTML format means we get a scrambled version of what you think you posted. Go do your homework this time (follow the Posting Guide) and come back with a question that helps us help you instead of asking for us to provide you with free work.
