patchGrob

<p>Methods for this generic should be defined for all <code>patch</code> subclasses
and should return a compliant <code>gtable</code> object ready to be combined with
regular plot objects. In general it is best to call <code>patch_table()</code> on the
object and add grobs to this as <code>patch_table()</code> will return a compliant
<code>gtable</code></p>

The 'ggplot2' package provides a strong API for sequentially
building up a plot, but does not concern itself with composition of multiple
plots. 'patchwork' is a package that expands the API to allow for
arbitrarily complex composition of plots by, among others, providing
mathematical operators for combining multiple plots. Other packages that try
to address this need (but with a different approach) are 'gridExtra' and
'cowplot'.
