How to use a variable created in a function in your console

Question

Let's say I have the following function:

create_X <- function() {

  x <- 14

}

Is there a way to give back the x variable to the console? So I can just hit x in my r console and then 14 pops up?

one way would be to use `<<-` instead of `<-` but it isn't really recommended — etienne, Nov 23 '15 at 09:36

Maybe this could help

create_X <- function() {
  assign("x", 14, envir=globalenv())
}

create_X()
print(x)
#14

You could also carefully use

create_X <- function() {
  x <<- 14
}

create_X()
print(x)
