The problem is that I am interested in all the warnings but after they have
been reported using the 'warnings()' command I am no longer interested in those
warnings but similar warnings (of the same type) may occur with subsequent
invocations and I am interested in these "new" warnings not the ones that have
been reported already. If 'warnings()' cleared out the warnings then it would
be ideal for me.
Thank you.
