title: Plotting to a file in R
body: <p>I'm a complete newbie to R, and none of the introductions I've seen cover how to use R when all you've got is the command line and no windowing system. My data's on a server, and I'm working with it via ssh. In gnuplot, you can set your "display" to be a PNG file on disk. How do I plot something to a file on disk from R? R-2.9.1 on CentOS, if it matters. Thanks!</p>
  
  <p>(Sorry if this is unusually basic, but I have the worst time Googling for quick answers with R. Cute name, impossible to search for.)</p>
