common_na_strings: Common string values for NA

common_na_stringsR Documentation

Common string values for NA

Description

This vector contains common values of NA (missing), which is aimed to be used inside naniar functions miss_scan_count() and replace_with_na(). The current list of strings used can be found by printing out common_na_strings. It is a useful way to explore your data for possible missings, but I strongly warn against using this to replace NA values without very carefully looking at the incidence for each of the cases. Please note that common_na_strings uses ⁠\\⁠ around the "?", "." and "*" characters to protect against using their wildcard features in grep. Common NA numbers are in the data object common_na_numbers.

Usage

common_na_strings

Format

An object of class character of length 26.
