Vectorize the assign function and create objects in global environment

Question

I would like to vectorize the assign function and create a set of arguments reflecting provided named vector that would be directly available in the .Glob

Answer 1

This functionality is already available via list2env:

From a named ‘list x’, create an ‘environment’ containing all list components as objects, or “multi-assign” from ‘x’ into a pre-existing environment.

list2env(as.list(vec_args), envir = globalenv())
ls()
# [1] "arg1"     "arg2"     "arg3"     "vec_args"

Something like the following would also work:

rm(list = ls())
vassign <- Vectorize(assign, c("x", "value"))
vec_args <- c(arg1 = 1, arg2 = 2, arg3 = 3)
vassign(names(vec_args), vec_args, envir = globalenv())
ls()
# [1] "arg1"     "arg2"     "arg3"     "vassign"  "vec_args"
