R Debugging Issue - Code not working

Question

Hi Im having issues with the following code:

RepLetter(n) <- function(){
    return(rep(letters[7]))
}

I want to create a function that returns the nth letter of the alphabet n times.

For example I would want "c" repeated like "c", "c", "c"

So I could type RepLetter(5) and R would return "e", "e", "e", "e", "e"

Answer 1

You have your function argument in the wrong place, and your arguments to rep are off.

Try this: 

RepLetter <- function(n){
  return(rep(letters[n],n))
}
