do.call specify environment inside function

Question

I\'m using the following construct in a package,

## two functions in the global environment
funa <- function(x) x^2
funb <- function(x) x^3
## called withi         


        

Answer 1

A slightly simpler version of @g-grothendieck's answer. Rather than using the function names, we just put the functions themselves into the list that is fed to lapply.

fun_wrap1 <- function(){
  funa1 <- function(x) x^2
  funb1 <- function(x) x^3
  lapply(list(funa1, funb1), do.call, list(x=3))
}

fun_wrap1()
