Let me admit at this point that I am not really sure that S4 classes
is the correct classification of such "@"-using extraction processes.
The documentation refers to "formal methods" and I don't yet have
enough knowledge to know that how tightly slots and formal classes are
linked with S4
As Ben Bolker's reply hints, our difficulty was that because we were
insufficiently knowledgeable regarding working with S4 objects such
as "a" and summary(a) object. Both mle2 and summary(a) produce S4
objects which need a different set of extraction technology. Although
I did not know

I had asked this question once before about a function in the NADA
package, and you provided this neat response:

An approach that may yield somewhat more self-documenting code would be
to examine either the fit object or the summary object with str and then
to access results by

eeep. Further comment on "etc" not possible at this tim
