I have data frame with two columns the first column is the number of children under the age of five that receive a treatment and the second column classifies the type of the treatment. I would like to know the total number of children under five who received treatment A, B, and C.

Treatment01 <- File01 %>% dplyr::filter(>of children under the age of five, Type of the treatment<)

I tried to use this code and

Treatment01 <- File01 %>% select(>of children under the age of five, Type of the treatment<)

I know dplyr::count() needs to be involoved but i couldn’t solve it.
