title: How do you make just the x-lab label italics and NOT the y-lab label as well? (in R)
body: <p>How do you make just the x-lab label italics and NOT the y-lab label as well?  The only
  command I can find (font.lab=3) makes both the x-lab and y-lab labels italics.  I am creating barplots in R that have specific names on the x and y axis.</p>
  
  <pre><code>barplot(y, main="Main Title",
      names=c("a", "b", "c"),
      xlab="Text that I would like to be in italics",
      ylab="Text that I do NOT want to be in italics",
      font.lab=3)
  </code></pre>
