case_when in mutate pipe

Question

It seems dplyr::case_when doesn\'t behave as other commands in a dplyr::mutate call. For instance:

library(dplyr)

case_when(mtcars         


        

Answer 1

library(dplyr) #loading the dplyr package

content150_fortified <- content150 %>% #creating a new variable
mutate(number_yn = case_when( #creating a new column using mutate
        number >= 18 & number <=25 ~ "no", # if number is "none", make number_yn "no"
        number!="none" ~ "yes"  # if number is not "none", make number_yn "yes"
        )
      )
