title: Plot points outside plotting region in R
body: <p>I want to add points(asterisks) outside the plotting region of a plot in R. However, the following code only allows points to be added inside the plotting region:</p>
  
  <pre><code>x = c(1:10)
  y = c(1:10)
  plot(x,y)
  points(11, 7, pch = 8)
  </code></pre>
  
  <p>How can I adjust code to allow the point to be plotted outside the plotting region?</p>
