title: How to include italics in the main heading to my graph?
body: <p>Here is the code I have atm;</p>
  
  <pre><code>plot(V1,V2,pch = 19, main = "Changes in absolute cell volume of Chlorella Alga over a 24hr period", xlab = "Stage in 24hr cycle", ylab = "Absolute cell volume(µm^3)", xlim = c(0,24), ylim = c(32.5,188))
  </code></pre>
  
  <p>I want the <code>Chlorella</code> part to be italicized as its the name of an organism. Any thoughts? </p>
