Dear community,
I have been struggeling for extensive amount of time now trying to understand what is going on here, when I perform my recipe() steps for my linear (glm) model using the Tidymodels framework. The recipe() step_dummy(all_nominal(), -all_outcomes()) was suggested by the usemodels() function Boilerplate Code for Tidymodels Analyses • usemodels .
When I commend out the step_dummy() the recipe() and prep() works fine, however its important to me that these categorical variables are dummyfied (..is that a word!?).
This is the first time I making use of and including a reprex in a question on stackoverflow, so please let me know if you need more information to assist on this matter.
I have looked everywhere, e.g. including a one_hot = TRUE or keep_original_cols argument in the step_dummy() but it does not seem to be effective.
It should be quite easy as it is a matter of renaming the generated columns as unique, but do not succeed. Here is the era.af_train set.
