setting options only inside functions
There is probably a more elegant way to do this, but you could write
it into dummy1():
dummy1 <- function()
{
...original function
options(old.options)
}
Alternatively, you could use ?tryCatch with the finally argument as a
call to options.

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?
Cheers
