common_na_strings | R Documentation |
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
.
common_na_strings
An object of class character
of length 26.
