| args {base} | R Documentation |
Displays the argument names and corresponding default values of a function or primitive.
args(name)
name |
a function (a closure or a primitive).
If name is a character string then the function with that
name is found and used. |
This function is mainly used interactively to print the argument list
of a function. For programming, consider using formals
instead.
For a closure, a closure with identical formal argument list but an
empty (NULL) body.
For a primitive, a closure with the documented usage and NULL
body. 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.
