Invoke a function with a list of arguments

Invoke a function with a list of arguments

Usage

invoke_fun(.fn, .args = list(), ..., .env = rlang::caller_env())

Arguments

.fn

A function, or function name as a string.

.args

A list or pairlist of argument values, or NULL.

...

Other arguments passed to the function.

.env

Evaluation environment for calls without arguments, or the parent of the temporary argument environment for calls with arguments. Captured expressions and caller-frame side effects use that temporary environment.

Examples

f <- function(x, y) {
  x + y
}
invoke_fun(f, list(x = 1, y = 2))
#> [1] 3
invoke_fun("f", list(x = 1, y = 2))
#> [1] 3
invoke_fun("f", x = 1, y = 2)
#> [1] 3
