Packages without explicit ‘NAMESPACE’ files will have a default one created at

so all packages will have namespaces. A consequence of this is that
‘.First.lib’ functions need to be
renamed, usually as ‘.onLoad’ but sometimes as ‘.onAttach’.
Couldn't R simply regard .First.lib as the appropriate function to
save many packages from
being needlessly changed?
It is doing that (see today's version of the NEWS), but the problem is
that it may choose the wrong one. If your package requires
initialization then yourpkg::somefun only works if the initialization
happens in .onLoad. But some packages only work if the initialization
happens when the package is attached. It's better for the author to
make the choice than for R to do it automatically.
