Clash between alr3 and AlgDesign. (Was: Re: Second & subsequent calls to function fails. Please help debug.)

Thanks, Duncan,

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

# BAD INTERACTION BETWEEN alr3 and AlgDesign

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.
