Applicability

The call of this R-function requires two inputs only:

Heatmap-like plot:

COMPLETENESS

Unit missingness

Segment missingness

Item missingness

The following implementation considers also labeled missing codes. The use of such a table is optional but recommended. Missing code labels used in the simulated study data are loaded as follows:

The function call above sets the analyses of causes for missing values to TRUE, includes system missings with an own code, and sets the threshold to 80%.
