title: Difference between R MarkDown and R NoteBook
body: <p>I am trying to understand at a high level what the differences between <code>R Markdown</code> and <code>R NoteBook</code>. I know they are interrelated but I would like to figure out how they are related. My understanding is this:</p>
  
  <p>I know R Notebooks are really R Markdown documents but I am confused about the terminologies.</p>
  
  <p>RStudio new file option has both <code>R Markdown</code> and <code>R NoteBook</code> and selecting either of them opens an <code>R Markdown</code> file but with minor differences. <strong>So just trying to figure out why are there two options and what is the difference between the two?</strong> </p>

  <p>I understand R Notebooks are newly introduced and R Markdown has been there for a while. Part of the confusion could be because I never used <code>R Markdown</code> before R Notebook was introduced so my related or more specific question is</p>
  
  <p><strong>What is R NoteBook doing differently than just using R MarkDown or what new capabilities is R NoteBook bringing?</strong></p>
  
  <p>All my hits on web search are pointing that R Notebook uses R Markdown but I did not find any help on what is specifically different between the two. </p>
