title: How do I set what plot() labels the x-axis with?
body: <p>I have a plot() that I'm trying to make, but I do not want the x-values to be used as the axis labels...I want a different character vector that I want to use as labels, in the standard way: Use as many as will fit, drop the others, etc. What should I pass to plot() to make this happen?</p>
  
  <p>For example, consider</p>
  
  <pre><code>d &lt;- data.frame(x=1:5,y=10:15,x.names=c('a','b','c','d','e'))
  </code></pre>
  
  <p>In barplot, I would pass <code>barplot(height=d$y,names.arg=d$x.names)</code>, but in this case the actual x-values are important. So I would like an analog such as <code>plot(x=d$x,y=d$y,type='l',names.arg=d$x.names)</code>, but that does not work.</p>
