check_dots_used: Check that all dots have been used
Description
Automatically sets exit handler to run when function terminates, checking
that all elements of ... have been evaluated. If you use on.exit()
elsewhere in your function, make sure to use add = TRUE so that you
don't override the handler set up by check_dots_used().
Usage
check_dots_used(env = parent.frame())
Arguments
env
Environment in which to look for ... and to set up handler.
# NOT RUN {f <- function(...) {
check_dots_used()
g(...)
}
g <- function(x, y, ...) {
x + y
}
f(x = 1, y = 2)
try(f(x = 1, y = 2, z = 3))
try(f(x = 1, y = 2, 3, 4, 5))
# }
