Dear list members, is it possible to set some options only inside a function so that the original options are restored once the function is finished or aborted due to an error? Until now I do something like: dummy=function() { old.options=options(error=dummy1()) .... options(old.options) } This works for most cases but when the function terminates because of an error and its last command is not run, error=dummy1() still remains as an option. Is there any way around this?
See ?on.exit: dummy <- function() { old.options <- options(error=dummy1()) on.exit(options(old.options)) .... } Uwe Ligges
