[Rd] Writing a package in which files must be sourced in a specific order

I only used characters a-z, so I didn't think that would be a problem.
 However, it turns out I had misnamed one of my files so that it
wasn't sorting correctly, and renaming it fixed the problem.
(Previously I had manully included that file first and I had forgotten
to remove it)

Thanks for the help.
