A waiver is a "flag" object, similar to <code>NULL</code>, that indicates the
calling function should just use the default value.  It is used in certain
functions to distinguish between displaying nothing (<code>NULL</code>) and
displaying a default value calculated elsewhere (<code>waiver()</code>)

An implementation of the grammar of graphics in R. It combines the
advantages of both base and lattice graphics: conditioning and shared axes
are handled automatically, and you can still build up a plot step by step
from multiple data sources. It also implements a sophisticated
multidimensional conditioning system and a consistent interface to map
data to aesthetic attributes. See http://ggplot2.org for more information,
documentation and examples.
