title: Saving plots in R as GIFs
body: <p>In R, I use function <code>savePlot</code> to save graphs into image files. But my colleague can only open .jpgs and .gifs (probably because he's on vacation, reading emails on his mobile phone). I hate to create jpegs because especially the boxplots looks very ugly (whiskers blurred etc.). But the <code>savePlot</code> function only supports the following types:</p>
  
  <pre><code>type = c("wmf", "emf", "png", "jpg", "jpeg", "bmp",
                    "tif", "tiff", "ps", "eps", "pdf")
  </code></pre>
  
  <h3>How can I save plot in GIF in R?</h3>
  
  <p>EDIT: if possible, ideal solution should work without installing ImageMagick (so that the R script is easily portable).</p>
