You know the feeling after long vacation and finally sitting in front of your favourite UI and even forgot how to write simplest “hello world” or “foo bar” function? Well, we got you covered! The reverse Hello world function is for all the people returning to the office after rather long vacation.

Create the function:

# reverse Hello World
hello_world <- function(print){
  if (print == "print"){
    print("Hello World")
  } else {
    cat("\rWell ...")
  }
}

And be confused for a split second, when you want to use this function correctly

Welcome back!

As always, the complete code is available on GitHub in  Useless_R_function repository. The sample file in this repository is here (filename: reverse_hello_world.R). Check the repository for future updates.

Happy R-coding and stay healthy!
