.drop_levels_keep_label

Helper function to drop unused levels from a factor variable while preserving
the <code>label</code> attribute. The base R <code><a href="/link/droplevels()?package=teal.slice&version=0.8.2" data-mini-rdoc="teal.slice::droplevels()">droplevels()</a></code> function strips all attributes
except <code>levels</code> and <code>class</code>, which causes the loss of variable labels that are
commonly used in clinical trial datasets.

internal

Data filtering module for 'teal' applications.  Allows for
interactive filtering of data stored in 'data.frame' and
'MultiAssayExperiment' objects. Also displays filtered and unfiltered
observation counts.
