title: How to change font family in a legend in an R-plot?
body: <p>I have a graph use the base graphics package. For the labels on specific points I use </p>
  
  <pre><code>   text(i, MSSAcar$summary[i,7]+.7, qld$LGA[i],
     col='red',  cex=.7, family='serif')
  </code></pre>
  
  <p>I have also used this in the plot for main titles and axis labels. They all come out as expected.</p>
  
  <p>When I add a legend I cannot seem to be able to set the font family.</p>
  
  <p>Can anyone help please.</p>
  
  <p>Thanks.</p>
