[Hodgess, Erin]

Arrgh!  That's it!  Thanks so much!

I like that modified function approach much better.

Thanks again,
Sincerely,

Erin, it seems you try to rename the whole package. In that case, in the first line of the NAMESPACE file, you also need to make the change, as it now is

Please see "Writing R Extensions" for the full infos you'll need.

A simpler approach to learn about timings might be to not rename the package, but add your modified function to it (and export those).
