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.
data for a reprex: Here's a discussion on setting up data for a reprex - make it run - include the minimal code required to reproduce your error on the data provided.
People should be able to copy and paste yourcode chunk
and get the same error.

? - minimal - strip away everything that is not directly related to your problem. This usually involves creating a much smaller and simpler set of code and data compared to that which created your issue.
Use the reprex
-package to Build Your Reproducible Example
When creating a reprex by hand, itâs easy to accidentally miss something that means your code canât be run on someone elseâs computer. Avoid this problem by using the reprex
-package.
The reprex
package will save effort for you and others who want to help.
