I am using the Credit dataset within the ISLR package in R. I was using the dataset and accidentally modified it creating new variables within it and messing up a variable it already had. Now when I run head(Credit) I get the modified dataset with all of my mistakes (the variable I altered and the variables I created all return "<data.frame [6 × 1]> " now. I have tried reloading the dataset, rerunning it, removing the new variables from my environment, and uninstalling the ISLR package and then reinstalling it. Nothing is working. Please help if you have any idea how I could fix this, I can't find anything on the internet that works.
