Manipulating Labelled Data
Work with labelled data imported from 'SPSS' or 'Stata' with 'haven' or 'foreign'. This package provides useful functions to deal with "haven_labelled" and "haven_labelled_spss" classes introduced by 'haven' package.
Online documentation: http://larmarange.github.io/labelled/
This package is built on the new class labelled introduced by haven package
and propose additional functions to manipulate labelled data.
Please note that this package is still under active development.
Missing values are currently not supported anymore by labelled package.

Some general principles
- Functions are intented to support
labelledmetadata structures only. However,to_labelledmethod allows to convert metadata from foreign and memisc packages. - Functions should, by default, modify metadata only (i.e. classes and attributes), except if explicitly expressed by the user.
