Hi,

You need to help us help you by providing the code you use. Obviously there is an unexpected symbol somewhere. (seems related to tibble)

Without a reproducible example, or at least a piece of code to see what you've done, it will very difficult to help further.

Advice: If you need more specific help, please provide a proper REPRoducible EXample (reprex) illustrating your issue.
