Sorry if this is well-known, but I can't find an answer or maybe just
don't
know how to ask Google the right question. If I run the following code in
R (3.1.1), I find that lattice:::xyplot.formula is still available (or
maybe just a promise to it ... ???) even though I've used detach and
unloadNamespace. Is there another step I'm missing?
require(lattice)
head(lattice:::xyplot.formula)
detach(package:lattice)
search() # No longer on search list
loadedNamespaces() # But namespace is still loaded
unloadNamespace("lattice")
loadedNamespaces() # Namespace not loaded
head(lattice:::xyplot.formula) # It is still accessible

Ah, here is the answer from the man page for ::: "...pkg:::name returns the value of the internal variable name. The namespace will be loaded if it was not loaded before the call, but the package will not be attached to the search path."

[R] How do I really, I mean really, unload a package?

Is there another step I'm missing?You just loaded it again. Read ?`:::` . The only way to make a package's namespace really unavailable is to uninstall it.> > require(lattice) > head(lattice:::xyplot.formula) > detach(package:lattice) > search() # No longer on search list > loadedNamespaces() # But namespace is still loaded > unloadNamespace("lattice") > loadedNamespaces() # Namespace not loaded > head(lattice:::xyplot.formula) # It is still accessible > > Kevin > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >PLEASE do: no HTML, do your homework before posting. -- Brian D.

[R] How do I really, I mean really, unload a package?
Running pkg::func or pkg:::func has the side effect of loading pkg's namespace, if it is not already loaded. Use remove.packages() to remove the package from your machine if you want to make its namespace unloadable.
