title: Vertical letters being clipped / cut off in base R graphics
body: <p>I'm having an issue with certain letters and numbers being cutoff/clipped when saved to png. It does not happen if I view the plots within RStudio. It happens with other fonts too besides Palatino, e.g. Book Antiqua.</p>
  <p>In the image below you can see that the 'e' is cut off when written vertically but not horizontally. Happens also to some of the tick labels. I have tried different image height/width combinations and it doesn't seem to change it. I checked if it is because the 'e's are at the end of words by putting them in the middle of words also, but seems to be a property of the character regardless of placement. I'm thinking it has something to do with par(&quot;cra&quot;) or one of those read-only parameters but haven't had success in finding a fix.</p>
  <p>I know that I could likely avoid this by using <code>ggplot2</code> but it is an old code relic and quite complicated to convert out of base plotting. Any suggestions for base plotting?</p>
  <p>Windows 10, R 4.0.3, RStudio 1.3.1093</p>
  <p>Thanks!</p>

  <pre><code>png(&quot;650_800.png&quot;, type=&quot;cairo-png&quot;, width=650, height=800, family=&quot;Palatino Linotype&quot;)
  plot(x=1,y=1)
  mtext(&quot;Absoelute  moistuere &quot;, side=1, cex=1.2)
  mtext(&quot;Absoelute  moistuere &quot;, side=2, cex=1.2)

  mtext(&quot;Absoelute  moistuere &quot;, side=4, cex=1.2)
  dev.off()
