Hi Bill, Without an example dataset it's hard to see exactly what you need to do. But you can get started by looking at the documentation for the reshape function (?reshape), and by looking at the reshape package. The reshape package has an associated web page (http://had.co.nz/reshape/) with links to papers and other information to help you get started.
