ggpairs change axisLabel font size
<p>When plotting internal <code>axisLabels</code> for <code>ggpairs</code>, if numbers are large, they get cropped off. </p>

<pre><code>fakedata &lt;- data.frame(Var1=rnorm(500, 3, 6), 
                       Var2=runif(500, 0, 5500), 
                       Var3=rpois(500, 6), 
                       Var4=rpois(500, 1500),
                       Var5=runif(500, 1, 60))

ggpairs(fakedata, axisLabels= "internal")
</code></pre>

<p>In the graph above, the y-axis labels for Var2 are cut off, and the x-axis numbers for Var4 run together. How would I change the font size? </p>

<p>I've seen from <a href="https://github.com/ggobi/ggally/issues/6" rel="nofollow noreferrer">this page</a> that it may be possible to find a fix by adding <code>theme()</code> from <code>ggplot2</code>, but I can't find a theme element that would represent font size for axis text. </p>
