title: R Markdown Bullet List with Multiple Levels
body: <p><a href="https://github.com/rstudio/cheatsheets/raw/master/rmarkdown-2.0.pdf" rel="noreferrer">https://github.com/rstudio/cheatsheets/raw/master/rmarkdown-2.0.pdf</a></p>
  
  <p>The cheat sheet above lists the following syntax to generate a bulleted list in R Markdown. <code>*</code> is the primary solid bullet. <code>+</code> is a secondary hollow bullet. And <code>-</code> is a tertiary solid square.</p>
  
  <p><code>
  * unordered list 
    + sub-item 1 
    + sub-item 2 
      - sub-sub-item 1</code></p>
  
  <p>After I render the output with knitr I don't get the expected output. I get what's shown below. The second and third lines are not indented. Only the very last line is indented, and only one indent instead of the expected two. And <em>all</em> bullets are the secondary <em>hollow</em> style. It's as if I put the following syntax into R Studio, but I didn't.</p>
  
  <p><code>
  + unordered list 
  + sub-item 1 
  + sub-item 2 
    + sub-sub-item 1</code></p>
  
  <p>How do I get what I intended, the first chunk of pasted syntax?</p>
