Find Library Location of Loaded Namespace

I'm looking to fetch what would be the lib.loc argument to library or loadNamespace, from a currently loaded namespace.

For attached packages this is relatively straightforward:

path.package("stats")  # get library location of loaded stats package

However, for a non-attached loaded namespace, the best I can come up with is:

getNamespace(x)[[".__NAMESPACE__"]][["path"]]

which happens to work on my R version, but has absolutely no guarantee of working in the future. I could also temporarily attach the package to use path.package, but that would potentially trigger attach hooks and I'd prefer to avoid that.

Anyone know of an equivalent to path.package for loaded but not attached namespaces?

You can use find.package :

it returns path to the locations where the given packages are found. If lib.loc is NULL, then loaded namespaces are searched before the libraries.
