title: Increase the space between two plots in RMD
body: <p>I have been trying to create a report in RMD, but the plots are appearing right after each other. I would like to add more spaces in-between each plots. I would really appreciate if you can assist me on this.</p>

    geom_bar(aes(fill = Sex)) 
  
  </code></pre>
