na_count() is a way to display the count and frequency of NA in data. It can be slow over large datasets.

na_count(data)

Acknowledgment

I learned this way of exploring data though the excellent webinar taught by Emily Robinson. The original code is hosted here.

Examples

if (FALSE) {
na_data <- data.frame(c1 = c(1, NA), c2 = c(NA, NA))
na_data %>% na_count()
}
