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

Evidently if we evaluate the functions in fun_wrap2 it works. The problem with the approach in the question is that the character strings get converted to functions inside one of the processing functions which changes the lookup path.

fun_wrap2 <- function(){

  funa1 <- function(x) x^2
  funb1 <- function(x) x^3

  nms <- c("funa1", "funb1")
  funs <- lapply(nms, match.fun)
  lapply(funs, do.call, list(x=3))

}

fun_wrap2()
