common_na_strings: 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.

Examples

dat_ms <- tibble::tribble(~x,  ~y,    ~z,
                          1,   "A",   -100,
                          3,   "N/A", -99,
                          NA,  NA,    -98,
                          -99, "E",   -101,
                          -98, "F",   -1)

miss_scan_count(dat_ms, -99)
miss_scan_count(dat_ms, c("-99","-98","N/A"))
common_na_strings
miss_scan_count(dat_ms, common_na_strings)
replace_with_na(dat_ms, replace = list(y = common_na_strings))
