lists_for_params.R

## Current pattern
function(myList){
  do_stuff_with(mylist$attribute1, myList$attribute2)
  do_stuff_with(mylist$attribute3, myList$attribute4)
}

## Desired pattern
function(myList){
  do_stuff_with(attribute1, attribute2)
  do_stuff_with(attribute4, attribute4)
}

Maybe it's something like:

myFunc <- function(...) {}
myFunc(unlist(myList)){}

This:

assign_vars <- function(x) {
  for (i in seq_along(x)) {
    assign(names(x)[[i]], x[[i]], envir = parent.frame())
  }
}

foo_bar <- function(x) {
  assign_vars(x)
  print(a)
  print(b)
}

a_list <- list(a = "hello", b = "world")
foo_bar(a_list)

#> [1] "hello"
#> [1] "world"
