Yes, that's the simplest way to do it.  It also usually works for 
testing to just source the file containing the fix, to get a new copy in 
the global environment.  This can sometimes fail if the function refers 
to other functions in the package that are not visible in the global 
environment, due to NAMESPACE hiding.  It's possible to manipulate the 
environment of the sourced function (and it's even possible to place it 
into the right place so it just works), but those usually aren't worth 
the trouble.
