Thanks, Duncan,

I started a new session under the suspicion that packages were clashing.

What now?

There's not much you can do; this is up to the package authors to fix. 
Some advice for them:

alr3, crossdes, faraway, and HH don't use a namespace.  This makes 
them very vulnerable to this sort of interaction, because they don't 
get to choose where the functions they use come from.  They should add 
one.

In my opinion, all packages should have namespaces, and I'd like to 
create a default one if the author doesn't.  (The default would be: 
import what is listed in the Depends clause, export everything.)  I 
don't think this will happen for 2.7.0, though package.skeleton might 
start creating one.
