sum_NA: Investigate missingness

In m-clark/tidyext: Tidy Extensions for Data Processing

Description

Investigate missingness

Usage

sum_NA(x)

sum_NaN(x)

sum_blank(x)

Arguments

x	a vector with multiple elements

Details

These functions return the number of NA, NaN, or blank values in a vector. Such information can serve as a diagnostic or used outright, e.g. in longitudinal settings. If you are dealing with singletons, you should just use the underlying function, e.g. is.na. For total blank values, the stringi package is required.

For more in this realm, I suggest you visit naniar.

Value

The number of non-elements so defined

Examples

library(tidyext)
sum_blank(c('    ', '', 'c', 'd'))
sum_NA(c(NA, '', 'c', NA))
sum_NaN(c(1:3, NA, NaN))
sum_NA(1:4)
