Not in general. detaching a package does not in general unload any
*library* (DLL, shared library, dynamic library, name depending on OS)
that was loaded. If there are no namespaces involved (a new feature of
1.7.0) it should give you the second version of the R code, and it did so
when I just did an experiment.
I'm afraid you will need to be more precise in your terminology and give
us more details.
