Subject: setting options only inside functions
In-Reply-To: <116783.45271.qm@web28202.mail.ukl.yahoo.com>
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.
