Hi, is there someone knows why I have this error when I use .drop=FALSE in my group_by ?
Error in `tidyselect_locs()`: ! Can't subset columns with `FALSE`. ✖ `FALSE` must be numeric or character, not `FALSE`.
It worked yesterday...
iris %>% filter(Species != "setosa") %>% group_by(Species, .drop = FALSE) %>% summarise(avg_petal_length = mean(Petal.Length))
