Hi! I had already been greatful about John Kane's response (using the car library's recode function), and I would have gone with that -- along with the promise to research any questions I may have in the future more intelligently.
Now I'm thinking it's not a matter of researching, but of plain and simple logic. Sorry to have made you guys help me with my ABCs, but I do see it as an opportunity to apreciate it as a lesson learned.
