How do I replace NA values with zeros in an R dataframe?

Question

I have a data frame and some columns have NA values.

How do I replace these NA values with zeroes?

Answer 1

The cleaner package has an na_replace() generic, that at default replaces numeric values with zeroes, logicals with FALSE, dates with today, etc.:

starwars %>% na_replace()
na_replace(starwars)

It even supports vectorised replacements:

mtcars[1:6, c("mpg", "hp")] <- NA
na_replace(mtcars, mpg, hp, replacement = c(999, 123))
