util_replace_codes_by_NA

Substitute all missing codes in a <a href="/link/data.frame?package=dataquieR&version=2.0.1" data-mini-rdoc="dataquieR::data.frame">data.frame</a> by <code>NA</code>.

Data quality assessments guided by a
'data quality framework introduced by Schmidt and colleagues, 2021'
<doi:10.1186/s12874-021-01252-7> target the
data quality dimensions integrity, completeness, consistency, and
accuracy. The scope of applicable functions rests on the
availability of extensive metadata which can be provided in
spreadsheet tables. Either standardized (e.g. as 'html5' reports) or
individually tailored reports can be generated. For an introduction
into the specification of corresponding metadata, please refer to the
'package website'
