As far as I can see sys.on.exit() does not work. The following
will give a non-null result in S, and seems about the simplest possible
usage.
test <- function() {
on.exit(print(1))
ex <- sys.on.exit()
str(ex)
cat("exiting...\n")
}
> test()
NULL
exiting...
[1] 1
Looking at the code suggests that on.exit is installing the code in
a different context from the one sys.on.exit is looking in, but this is
daunting for non-experts.
The help page does not say what this is supposed to do, of course, but
I assume it is intended to retrieve the on.exit expression, as in S.
