[Rd] setting option in function

[Charles Geyer]

is it possible to set an option inside a function ((I want to set
na.action = na.fail) and have the previous state restored if there is
an error so that the function doesn't change the option behind the
user's back?

Sorry if this has been answered before, but this subject is hard to Google.
