I have to insert 0 into NA and missing values in a csv file

Hi Rock,

If I understand correctly, if budget is NA, you want to change the value of screens to 0. Have you considered using case_when inside of mutate?:

library(tidyverse)

moviedata <- moviedata %>% 
  mutate(screens = case_when(
    is.na(budget) ~ 0,
    TRUE ~ screens
  ))

If this isn't what you're looking for, can you please share a reprex (reproducible example)? This will ensure we're all looking at the same data and code. A guide for creating a reprex can be found here.
