Columns the instrument declares that the responses left out

A partial export gives a quality report every column it holds, and none of the ones it dropped. This names the declared columns that never arrived, so a missingness figure can be read against what was expected. They count as missing for every respondent in quality_report()'s rates.

Usage

sf_missing_columns(x, ...)

Arguments

x

An sframe_quality_report object.

...

Passed to methods.

Value

A character vector of column names, empty where the export carried every declared column.
