Semantic labelled vector class

The class haven_labelled_defined represents a semantically enriched labelled vector created by defined().

Objects of this class inherit from:

• [haven:labelled]() for numeric, character, and factor data;

• Date for temporal dates;

• POSIXct and POSIXt for timestamps;

• logical for boolean data.

The class tag enables S3 method dispatch for:

• [as_character()]

• [as_numeric()]

• [as_logical()]

• as.Date

• as.POSIXct

• print.haven_labelled_defined

• summary.haven_labelled_defined

Users normally do not construct this class directly; it is returned as the result of calling defined().
