labelled

This package is built on the new classes haven_labelled and haven_labelled_spss introduced by haven package to handle labelled variables imported from SPSS, Stata and SAS. The labelled package propose several functions to manipulate such vectors and their metadata: variable labels, value labels and user-defined missing values.

Breaking changes introduced in version 2.0.0

Following version 2.0.0 of haven, labelled() and labelled_spss() now produce objects with class “haven_labelled” and “haven_labelled_spss”, due to conflict between the previous “labelled” class and the “labelled” class used by Hmisc.

A new function update_labelled() could be used to convert data imported with an older version of haven to the new classes.

Some general principles

  1. Functions are intented to support labelled metadata structures only. However, to_labelled method allows to convert metadata from foreign and memisc packages.
  2. Functions should, by default, modify metadata only (i.e. classes and attributes), except if explicitly expressed by the user.
