| as.function {base} | R Documentation |
as.function is a generic function which is used to convert
objects to functions.
as.function.default works on a list x, which should contain the
concatenation of a formal argument list and an expression or an
object of mode "call" which will become the function body.
The function will be defined in a specified environment, by default
that of the caller.

The desired function.
For ancient historical reasons, envir = NULL uses the global
environment rather than the base environment.
Please use envir = globalenv() instead if this is what you want,
as the special handling of NULL may change in a future release.
