You mentioned you didn't know why the last condition was "TRUE".
That's the case because a condition of "TRUE" is always going to evaluate to TRUE, and therefore acts as the catch-all for the final condition.

But I still wonder if we need to 'vectorize' all the values before being able to use case_when every time we have a "chr/fctr" variable
