[R-pkg-devel] Recommendations about adding options to a package in order to change default values of some functions on-the-fly

I would like to change the default value of some arguments of some
functions in a package of mine. I don't want to change explicitly the
calls in the many scripts that have been written. For example, I would
to change the delimiter in all write.mytable() without changing any
calls it and without changing the default value currently assigned to
that delimiter in the declaration of this function. What I would like is
to add a command at the beginning of the scripts that says "since now,
the delimiter is ;".
I am thinking about setting global options that those functions will
read and use to overwrite the default values. Of course the
write.mytable function has to be modify to exploit these settings, but
none of the scripts. I think about something similar to the par() and
I noticed the settings package, but I would like to know if there is a
simple and recommended solution without adding any dependency.
Hope my question is clear.
Thanks for any advice,
