Dear professor,

the picture was followed. How up debug?

Thanks.

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.

The API has changed since that post We'll update it.

The error message has the solution:

✖ This function does not work with grouped data frames.
ℹ Apply dplyr::ungroup() and use the .by argument.

so use

combined %>%
    cal_plot_breaks(Class, .pred_good, .by = c(source))
