lfactors-package

<p>Similar to a factor, the user defines levels and labels when 
creating an <code>lfactor</code>. This is especially useful when
labels are long, and users know the levels well.</p>

Provides an extension to factors called 'lfactor' that are similar
to factors but allows users to refer to 'lfactor' levels by either the level or
the label.
