title: integrate points into base R plot in respect to second axis
body: <p>With a very simple example, I wish to create a boxplot of distribution X and then add the points of Y with respect to a second vertical axis. can someone offer some advice or assistance?</p>
  
  <pre><code>set.seed(123)
  A &lt;- rnorm(100, 4, 1)
  B &lt;- rnorm(100, 25, 5)
  
  # create our simple boxplot
  boxplot(A, ylim=c(0,10))
  
  # then our second axis
  axis(4, at = seq(0, 10, by = 1), labels= seq(0, 100, by = 10),las=2)
  
  # want to create vertical poins for each B value
  # possibly with some jitter
  par(new = TRUE)
  points(B, bty = "n", xlab = "", ylab = "", ylim=c(0,100), col="green")
  </code></pre>
  
  <p>The desired output should look like</p>
