How to disable “Save workspace image?” prompt in R?

Question

When I exit the interactive R shell, it displays an annoying prompt every time:

>
>
Save workspace image? [y/n/c]: n

I\'m always answering \"no\" to it

If, like me, typing out a whole pair of brackets seems like too much effort to exit the repl you can try this:

exit <- structure(list(), class = "exit_command")

print.exit_command <- function(...) {
  q("no")  # exit without saving
}

This creates a new class, which causes R to exit when attempting to print said class. The upshot being that if you run exit in the R repl, the whole thing will exit (because it tries to print it).

NB: You can add it to ~/.Rprofile to load at the start of every session.
