Invoke a Function Call
Description
An alternative interface for do.call()
, similar to the deprecated function in purrr.
This function tries hard to not evaluate the passed arguments too eagerly which is
important when working with large R objects.
It is recommended to pass all arguments named in order to not rely on positional
argument matching.
Usage
invoke(
.f,
...,
.args = list(),
.opts = list(),
.seed = NA_integer_,
.timeout = Inf
)
Arguments
.f |
(function() )
Function to call.
|
... |
(any )
Additional function arguments passed to .f .
|
.args |
(list() )
Additional function arguments passed to .f , as (named) list() .
These arguments will be concatenated to the arguments provided via ... .
|
.opts |
(named list() )
List of options which are set before the .f is called.
Options are reset to their previous state afterwards.
|
.seed |
(integer(1) )
Random seed to set before invoking the function call.
Gets reset to the previous seed on exit.
|
.timeout |
(numeric(1) )
Timeout in seconds. Uses setTimeLimit() . Note that timeouts are only
triggered on a user interrupt, not in compiled code.

Examples
invoke(mean, .args = list(x = 1:10))
invoke(mean, na.rm = TRUE, .args = list(1:10))
