Labelled package for R

This package is built on the new classes haven_labelled and haven_labelled_spss introduced by haven package and propose additional functions to manipulate such labelled data.

BREAKING CHANGES

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.

Installation

From CRAN:

install.packages("labelled")

Latest version from GitHub:

devtools::install_github("larmarange/labelled")

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.
