<p><code>print</code> prints its argument and returns it <em>invisibly</em> (via <code><a rd-options="" href="/link/invisible?package=base&version=3.6.2" data-mini-rdoc="base::invisible">invisible</a>(x)</code>). It is a generic function which means that new printing methods can be easily added for new <code><a rd-options="" href="/link/class?package=base&version=3.6.2" data-mini-rdoc="base::class">class</a></code>es.</p>
