args(name)

a function (a closure or a primitive).

Details
This function is mainly used interactively.
For programming, use formals instead.
Value
A function with identical formal argument list but an empty body if given a closure.
A function with the documented usage for a primitive: note that in
almost all cases primitives do not make use of named arguments and
match by position rather than name. (rep and seq.int
are exceptions.)
NULL in case of a non-function.
