ARD Attributes

Source: R/ard_attributes.R

Add variable attributes to an ARD data frame.

  • The label attribute will be added for all columns, and when no label is specified and no label has been set for a column using the label= argument, the column name will be placed in the label statistic.

  • The class attribute will also be returned for all columns.

  • Any other attribute returned by attributes() will also be added, e.g. factor levels.
