Hi Valerie, Are you using your own data or data provided by the authors?
If the latter, where can we get it? If the former, please provide a reproducible example using dput() to include some of your data. Also, please resend your message with HTML mail turned off so we can actually read it. Providing a reproducible example makes it possible for us to figure out what went wrong.
