title: Moving color key in R heatmap.2 (function of gplots package)
body: <p>I read the heatmap.2 help manual a couple of times now, and also in various online tutorials I didn't read about a way to move the color key to a different position.
  Now, I am wondering if it is even possible? </p>
  
  <p>The color key is in the upper left corner by default if you are using the heatmap.2 function from the gplots package.</p>
