Set missing value attribute according to the missing value lookup list. If no lookup list exist in tha tsExport object or overwrite_lookup is TRUE create a new lookup list for for variables whose values match certain labels or numeric values that are generally considered as missing.
spss_missings_tsExport(
tsExport,
missing_labels = missing_labels_default,
missing_values = NULL,
overwrite_lookup = TRUE
)tsExportdata.
character vector of value labels that are generally considered as missing values.
numerical vector of values that are generally considered as missing values.
Boolean Should a new missing value lookup list created when the tsExportdata object already contains one?
tsExportdata with newly created missing value lookup list in
export_options and `na_values` attributed variables.
When a new missing value lookup list is created, it uses the value
label lookup list as foundation. The value lookup list get's filtered for
matching labels or values that are provided as arguments to the function.
As default, missing_labels_default is used to create the lookup list.
Afterwards variables found in the missing lookuplist, are converted to
'haven_labelled_spss' class which uses the the `na_values` attribute to define
missing values. This attribute is set for each variable found in the
missing value lookup list.
