do_call: Call a function with a list of arguments

In plotthis: High-Level Plotting Built Upon 'ggplot2' and Other Plotting Packages

Call a function with a list of arguments

Description

A faster alternative to do.call, especially when there are large objects in the argument list. Named arguments are looked up by symbol in the evaluation environment rather than being copied into the call, which avoids the copying overhead of base::do.call. Unnamed arguments are embedded in the call directly and do not benefit from this optimization. Borrowed from Gmisc::fastDoCall.

Usage

do_call(what, args, quote = FALSE, envir = parent.frame())

Arguments

what	either a function or a non-empty character string naming the function to be called.
args	a list of arguments to the function call. The names attribute of args gives the argument names.
quote	a logical value indicating whether to quote the arguments.
envir	an environment within which to evaluate the call. This will be most useful if what is a character string and the arguments are symbols or quoted expressions.

Value

The result of the function call
