Multiple arguments for "face" in element_text
<p>I am adding aesthetics to a plot in R using themes in ggplot2.  I would like to make the x axis text both bold and italic.</p>

<p>I know I can use:</p>

<pre><code>theme(axis.text.x = element_text(face ="bold"))
</code></pre>

<p>to make the axis text bold and:</p>

<pre><code>theme(axis.text.x = element_text(face ="italic"))
</code></pre>

<p>to make it italic. </p>

<p>But how would I make it both bold and italic?</p>

<p>None of these do the job</p>

<pre><code>theme(axis.text.x = element_text(face ="italic", "bold"))
theme(axis.text.x = element_text(face =c("bold", "italic")))
theme(axis.text.x = element_text(face = "bold", face = "italic"))
theme(axis.text.x = element_text(face = "bold" &amp; "italic"))
</code></pre>

<p>Any help appreciated.</p>
