title: Cannot cite using bibtex in blogdown?
body: <p>My question is similar to <a href="https://stackoverflow.com/questions/46414520/how-to-cite-using-bibtex-in-blogdown/46488860#46488860">How to cite using bibtex in blogdown?</a></p>
  
  <p>However I have used Rmd file to cite but still not work. I don't know what's wrong and what I should add in the Rmd file.</p>
  
  <p>I hope to cite Casella's Statistical Inference book in text and generate a reference.</p>
  
  <p>For example</p>
  
  <ol>
  <li><p>I created si.bib file from google scholar and put it into /content/post folder.</p></li>
  <li><p>I created a Rmd file called "cite something" and included code like this </p>
  
  <pre><code>---
  title:  cite something
  author: ''
  date: '2018-05-17'
  slug: cite-something
  categories: []
  tags: []
  bibliography: [si.bib]
  link-citations: true
  ---
  @si
  # Reference
  </code></pre></li>
  </ol>
  
  <p>I hope to create something like this</p>
