metacore |
A metacore object to get the codelist from. If the variable has different codelists for different datasets the metacore object will need to be subsetted using 'select_dataset' from the metacore package. |
var |
Name of variable to check |
na_acceptable |
Logical value, set to 'NULL' by default, so the acceptability of missing values is based on if the core for the variable is "Required" in the 'metacore' object.
