title: How to change into italic style one letter in R plot without adding a space
body: <p>I have almost done what I need that is basically having "q" and "Å" in italic in the x-axis label. However, I want to avoid the space before and after the "Å"... It is probably a silly question but I have been trying to remove the "~" and something else without success. Where am I wrong? Basically, the result should be:
  "Scattering factor, <em>q</em>(1/<em>Å</em>)" instead of "Scattering factor, <em>q</em>(1/ <em>Å</em> )"</p>
  
  <pre><code>plot(1, 1, xlab= expression("Scattering factor,"~italic(q)~"(1/"~italic(Å)~")"))
  </code></pre>
  
  <p>Thank you.</p>
