This video was very helpful, thanks! One question, I have a categorical variable (season) in my dataset and the plot is excluding one of the seasons. Do you know why that might be, and will it cause issues for my model?

Are there any NA values in the season variable? Often I've found that variables won't plot if you have missing values.
