na_range_to_values(x)

is.na_range_to_values(x)

`x`	A labelled_spss or labelled_spss_survey vector

na_range_to_values() tests if the function needs to be called for na_values harmonization. The na_range is often missing and less likely to cause logical problems when joining survey answers.

A x with harmonized na_values and na_range attributes. If min(na_values) or max(na_values) than the left- and right-hand value of na_range, it gives a warning and adjusts the original na_range.

Other variable label harmonization functions: harmonize_values(), harmonize_waves(), label_normalize()

             "DON'T KNOW" = 8,
