Could you provide a little of context? Ideally, could you ask this with a minimal REPR oducible EX ample (reprex) ? A reprex makes it much easier for others to understand your issue and figure out how to help.
Why reprex?
Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it and feel your pain. Then, hopefully, folks can more easily provide a solution.
What's in a Reproducible Example?
Parts of a reproducible example:
background information - Describe what you are trying to do. What have you already done?
complete set up - include any library() calls and data to reproduce your issue.
