Editing a package with a NAMESPACE in place

I would like to edit a function from a package that uses a NAMESPACE, but in place (after the package is loaded). As a simple example, I would like to add a browser() call to a line in one of the functions for debugging purposes. Since the function is in the package namespace, I can't do that directly by simply making a copy of the function and editing it--that copy doesn't get used. I tried assigning into the package environment, but it is locked, it appears. How do I go about doing this without changing the package source, then reinstalling and reloading?
See the section on debugging in `Writing R Extensions' (which has this exact example). Most easily by trace(), but you can also use fixInNamespace().
