update() is generic, so the recommended approach would be to write a method
for your objects.
Creating your own function update() in a package would probably not break too
much, as namespaces would protect most functions using the generic in stats.
But it could be very confusing to users.
Maybe. update is generic with a netral set of argument names; on the
other hand, the _documentation_ of update is not generic -- it is
specific to updating models. So there is opportunity for confusion
from that direction.

Dear all,
I wonder if it is "bad style" (or something worse) to create an "update"
function which does not work on model objects of the lm, glm etc. type.
Specifically, I have some graph objects (graphs as mathematical objects,
not as displays) which I want to alter and for that purpose I thought of
writing an update function. Would doing so violate a "deeper philosophy" in
the R system or have other unfortunate consequences. If so, I'm happy to
hear other suggestions...
Regards
Søren
