R help - May 2010 - list of complex objects?

Hi all,

If I would like to make a list of complex objects -- in my 
case, phylogenetic trees, but it could be e.g. statistical 
results from something like lm, or whatever -- how can I put 
them into a list?

When I try the obvious methods, e.g. cat, append, list, 
etc., I seem to get weird behaviors where R is trying to 
merge the subfields within the objects or something.

Any help much appreciated.  Cheers!!
Nick

Perhaps you can give us a reproducible example that shows

a) what you tried
b) what happened
c) what you expected to happen
