title: heatmap with values and some additional features in R
body: <p>I am trying to make a heatmap in R, that along with the fill should also show the values and along with filling, should also include a row and column without applying fill on them.</p>
  
  <p>My data looks like this</p>

  <p>My data doesn't only represent the monthly values but also take in consideration the monthly sum and averages. Making the heat map only with monthly values is not that difficult and I have already done that.</p>
  
  <p>the link to my work is here: <a href="https://drive.google.com/file/d/1ndgWY_E2vKanU7qIaAGxsSe6txRMAg00/view?usp=sharing" rel="nofollow noreferrer">code</a>, <a href="https://drive.google.com/file/d/1JWDEFW7HJfJA3vnwRRVIm5LycdEQNtgx/view?usp=sharing" rel="nofollow noreferrer">heatmap</a></p>
  
  <p>I don't want to include last row and column in the heatmap that represent the sum and average values. I am not sure how can I do that. Please guide me to this. I want to perform this task either with ggplot2 or heatmap package.</p>
  
  <p>I want something like this: <a href="https://i.stack.imgur.com/huTA3.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/huTA3.jpg" alt="enter image description here"></a></p>
