drop_na {tidyr}

Drop rows containing missing values

Description

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

Usage

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()
df %>% drop_na(x)

vars <- "y"
df %>% drop_na(x, any_of(vars))
