Mistake in creating QQPlots etc

Hi,

Welcome to the RStudio community!

It seems there is an encoding problem, likely because of the special characters, although you ensured the data is in UTF-8.

Could you generate a reprex with a small sample dataset so we can try and run the code ourselves. A reprex consists of the minimal code and data needed to recreate the issue/question you're having. You can find instructions how to build and share one here:

Good luck,
PJ
