Given SpatialPolygons* object <code>x</code> and <code>y</code>

<code>x + y</code>  --  same as <code><a href="/link/merge?package=raster&version=1.9-44" rd-options="" data-mini-rdoc="raster::merge">merge</a></code>

<code>x - y</code>  --  same as <code><a href="/link/gDifference?package=raster&version=1.9-44&to=rgeos" rd-options="rgeos" data-mini-rdoc="rgeos::gDifference">gDifference</a></code>

<code>x * y</code>  --  same as <code><a href="/link/crop?package=raster&version=1.9-44" rd-options="" data-mini-rdoc="raster::crop">crop</a></code>

Using functions from rgeos, with some added functionality to keep attributes.
