None. That's what require() or library() or source() are for.

You need to read more carefully:
?ls
?objects
?search

`ls` with default settings only lists data and function objects that the user has defined. The history mechanism could be used to restore packages that were loaded during a session.
?history
You should be able to see this by looking at what ls() produces. It does not generally return a listing of items in loaded packages.
