Hi I built a random forest model with a character predictor transformed with step_dummy. However, when I was doing last_fit with splits, the model failed to generate predictions with warning Error: Missing data in columns:.
I want to know how to fix this issue.
Thanks,
Felix
Can you please provide a minimal reprex (reproducible example)? The goal of a reprex is to make it as easy as possible for me to recreate your problem so that I can fix it: please help me help you!
If you've never heard of a reprex before, start by reading "What is a reprex", and follow the advice further down that page.
