All,
1. Is there a command that tells you what libraries are loaded?
Loaded is a fluid idea** in a namespace world, but search() will let
you know what's on the search path (accessible to you)
There is also unloadNamespace() which may be more complete, although I
do not think complete sanity is guaranteed.

2. How do you remove a library that has been loaded?
detach() can do it, but there might be lingering effects. The only
true way is to restart your session.
3. If you have loaded a library that masks previously loaded
objects, how
can you tell which object is being run? In Matlab, I would run
"which f" to
determine the location of the file f that will be run. Is there a
similar
procedure in R?
Not exactly, but take a look at conflicts() and the :: operator.

**Well, loading is a particular step in the package management
process, but probably not what you are thinking of.
