Drop rows containing missing values

Source: R/drop-na.R

drop_na() drops rows where any column specified by ... contains a missing value.

drop_na(data, ...)

Arguments

data

A data frame.

...

<tidy-select> Columns to inspect for missing values. If empty, all columns are used.

Details

Another way to interpret drop_na() is that it only keeps the "complete" rows (where no rows contain missing values). Internally, this completeness is computed through vctrs::vec_detect_complete().

Examples

df <- tibble(x = c(1, 2, NA), y = c("a", NA, "b"))
df %>% drop_na()
#> # A tibble: 1 × 2
#>       x y    
#>   <dbl> <chr>
#> 1     1 a    
df %>% drop_na(x)
#> # A tibble: 2 × 2
#>       x y    
#>   <dbl> <chr>
#> 1     1 a    
#> 2     2 NA   

vars <- "y"
df %>% drop_na(x, any_of(vars))
#> # A tibble: 1 × 2
#>       x y    
#>   <dbl> <chr>
#> 1     1 a
