Hi CianStryker, you pasted in a screenshot of your reprex. When you reprex was created, it should have added that text to your machine's clipboard. Meaning after your reprex() command, all you need to do is paste into this thread.
Hi sophiafreuden, it looks like you pasted in a screenshot of your reprex instead of the text that creates that. WHen you ran reprex(), it actually stored that text to your clipboard.
Here's the part of Jenny Bryan's video intro on how this works.
