A warning here: tryCatch(expr, warning=...) will catch warnings and
interrupt 'expr' (as if an error occured), whereas
withCallingHandlers(expr, warning=...) does not do this.

I've just been nosing around the source code in errors.c, and it
doesn't look good.

Yes, thanks for pointing it out. However, I'm actually looking for a way to
catch all warnings in a whole (interactive) session. Can warning.expression
be used for that?

No, sorry, this does not work. Try this, if you like:
myfunc <- function () {
warnings ()
}
options (warning.expression=quote (myfunc ()))
warning ("test")

tryCatch ()
and
withCallingHandlers ()
are a whole different story, as far as I understand them
You might be interested in 'tryCatch' to catch warnings.

Hi!
I'm trying to catch all warning-messages for special handling. It seems
options (warning.expression=myfunc ()) can be used for that. However, the
question is: How can I get at the actual warning in myfunc ()? Apparently in
S, you can use .C("get_last_message") for that. Is there a similar m
