dplyr replacing na values in a column based on multiple conditions

Question

I have this data with two NA values in the Occupation column and I am trying to use dplyr to replace the values with the word Pensioner

Answer 1

You can use case_when like this:

data %>% 
  mutate(Occupation = case_when(is.na(Occupation) & Yrs_Empleo <= -999 & Organisation == "XNA" & Income_type == "Pensioner" ~ "retired",
                                TRUE ~ Occupation))

      Yrs_Empleo  Occupation           Organisation          Income_type
