In either case, you'll have to rebuild the package with your modified 
function in it or with a modified NAMESPACE file which changes the exports.

In any event, as I told you yesterday, it would likely be more valuable 
for you to examine the audit environment created up to the point that 
apply.paramset's included combine function fails to figure out where 
your strategy is failing.
