I am trying to submit my answers to the swirl program (R programming - Functions unit). No matter what answers I put in, even the ones that I know are correct, it asks me to repeat the question.

For example,

"Below we will create a function called boring_function. This function takes the argument x as input, and returns the value of x without modifying it. Delete the pound sign in front of the x to make the function work! Be sure to save this script and type submit() in the console after you make your changes."

    boring_function <- function(x) {
      #x
     }

So I submit:

    > boring_function <- function(x) {
       x
     }
    > submit()

And it gives me this error:

"Sourcing your script... Not quite! Try again. Make sure to delete the pound sign so the last expression in the function is just x."

If I skip this question, and go on to later questions, it does the same thing.

Do I need to uninstall/reinstall the swirl package or is there some other problem?

Thanks in advance.

  • Could you run `sessionInfo()` and edit to include the output? – C8H10N4O2 Sep 23 '16 at 18:26
  • Also I would try reinstalling the package before asking the question. You should check the easy stuff first. P.S. welcome to SO--for a first question you have clearly put some effort into describing the problem. – C8H10N4O2 Sep 23 '16 at 18:28
  • I reinstalled the package but I am still getting the same error. I added the SessionInfo() information in the post above. – clupea Sep 27 '16 at 11:44
