title: How to change the label size of an R plot
body: <p>I`m making a cluster plot from my data. I have the entire plot finished but my label text is to large to be able to properly read the plot. Anyone any idea how to make labels smaller.</p>
  
  <p>I am using the package "sparcl", and my function is:</p>
  
  <pre><code>ColorDendrogram(fit,y=col.int, main = "Clusters from 216 samples",
                  branchlength = 0.20, labels = fit$labels, xlab = NULL,
                  sub = NULL, ylab = "", cex.main = NULL)
  </code></pre>

  <p>as you can see the branch text is to big and they fall over each other. I want the text of the leaves to be 25% smaller. I already looked at the documentation of the Sparcl package but that doesn't seem to work.</p>
