I can't copy and paste your example right out of you email and into an
R session.
?dput
and then see if you can copy and paste it into an R session and make
it work. That way it is easier for everyone and you have a better
chance of getting helpful responses.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
