I am using the code below to count how many time the id appears in the manager_id column :-
mutate(ManagerCount = map_int(.x = WpA_Rscript$id, .f = ~ sum(WpA_Rscript$manager_id == .x, na.rm = TRUE)))
However when I use this code i get the following error:-
Error in Ops.factor(WpA_Rscript$manager_gpid, .x) : level sets of factors are different
Can anyone help me to understand what the issue is here?
