Recode multiple columns using dplyr

Question

I had a dataframe where I recoded several columns so that 999 was set to NA

dfB <-dfA %>%
  mutate(adhere = if_else(adhere==999, as.numeric(NA), adhere         


        

Answer 1

Now that funs has been depreciated in dplyr, here's the new way to go:

z <- y %>%
  mutate_if(is.integer, as.numeric) %>%
  mutate_at(vars(y1:y2), list(~recode(.,`999` = NA_real_)))

Replace funs with list and insert a ~ before recode.
