title: Create an HTML file with R
body: <p>What I'm wondering is, would it be possible to create an HTML file from R ? I will be setting up R to work on the server side, and it will be making an heatmap overlay, and hopefully if it is possible to make an HTML file from R, I can just add in the image and set it up so it will be using Google maps, using the heatmap overlay.</p>
  
  <p><a href="https://developers.google.com/maps/documentation/javascript/examples/overlay-simple" rel="nofollow">This is the code</a> I'm looking at and in there the overlay is given two coordinates, North east and south west, along with a center to specify where the map is.</p>
  
  <p>In R when the overlay has been created, I can also save the coordinates, north east and south west along with the center of where the map should go. But what if I don't make the HTML file in R? How can I get these coordinates and delete previous overlay and place the new one on top and update it with the new coordinates?</p>
