title: How to make a heat map in R based on a gif of the human body?
body: <p>I have a gif of a human body and need to plot a heat map on it . The data to be used is in R</p>
  
  <p>I have found instructions on how to import a gif but it is the getting my data onto the gif that I am unsure of.</p>
  
  <p>I presume I would need to put the gif on a grid at first and then get some co-ordinates and then assign the data to the relevant co-ordinates ?</p>
  
  <p>For example if the head was located at (5,10), the stomach at (5,5) , the right knee at (4,3) etc etc on a grid .</p>
  
  <p>Is there a package people use for this or is it just a task of programming strictly in R with no packages ? or do you use another resource ?</p>
