title: What happened to the windows() function
body: <p>Sorry if the answer is obvious. I'm using the R book (2nd ed) and they describe how to use the windows() function to change the window size. E.g., you could specify: </p>
  
  <pre><code>windows(7,4)
  par(mfrow=c(1,2))
  </code></pre>
  
  <p>And now you could nicely ask for two plots and they wouldn't be "squished" horizontally. </p>
  
  <p>However, when I went to invoke windows(), I can see the function is no longer a part of the grDevices package. </p>
  
  <p>Any idea how to adjust the window size??</p>
