do.call2

Execute a function call similar to do.call.

Description

This function is supposed to be a replacement for do.call in situations where you need to pass big R objects. Unlike do.call, this function allows to pass objects via ... to avoid a copy.

Usage

do.call2(fun, ..., .args = list())

Arguments

`fun`	[`character(1)`] Name of the function to call.
`...`	[any] Arguments to `fun`. Best practice is to specify them in a `key = value` syntax.
`.args`	[`list`] Arguments to `fun` as a (named) list. Will be passed after arguments in `...`. Default is `list()`.

Value

Return value of fun.

Examples

## Not run: 
  library(microbenchmark)
  x = 1:1e7
  microbenchmark(do.call(head, list(x, n = 1)), do.call2("head", x, n = 1))

## End(Not run)
