title: Changing plot label sizes in R, cex is not working
body: <p>I am making a very simple plot in R and would like the change the font size on the y-axis (the years).  I have used all the cex. commands, and can change everything except these years.</p>
  
  <p>Here is my matrix (inputm):  </p>
  
  <pre><code>     2010  2011
  CC 0.5550 0.480
  P  3.6700 3.865
  PF 1.4625 1.685
  </code></pre>
  
  <p>And my code:</p>
  
  <pre><code>barplot(inputm,beside=T, horiz=TRUE, xlim=c(-7,7), 
  col=c("black","blue","red"), xlab="Mg C/ha", cex.axis=2)
  </code></pre>
  
  <p>I can get the x-axis labels to change, but not the y.  What am I missing here?</p>
