library(dplyr) df <- tibble(x = c(1, 2, NA), y = c("a", NA, "b"), z = list(1:5, NULL, 10:20)) df %>% replace_na(list(x = 0, y = "unknown"))
#> # A tibble: 3 x 3 #> x y z #> <dbl> <chr> <list> #> 1 1. a <int [5]> #> 2 2. unknown <NULL> #> 3 0. b <int [11]>
# NULL are the list-col equivalent of NAs df %>% replace_na(list(z = list(5)))
#> # A tibble: 3 x 3 #> x y z #> <dbl> <chr> <list> #> 1 1. a <int [5]> #> 2 2. <NA> <dbl [1]> #> 3 NA b <int [11]>
df$x %>% replace_na(0)
#> [1] 1 2 0
df$y %>% replace_na("unknown")
#> [1] "a" "unknown" "b"
