This is just a warning — not necessarily an error. The computer is telling you that you’ve created a new dataframe from parts of the old one, and that the old data frame won’t inherit changes you make to this new one. You can ignore it and everything will work fine.

If you add <.copy()> to the code where you assign a slice of the data frame to a new object, it’ll also disappear.
