title: How do I cite papers with multiple authors using YAML metadata with RMarkdown + knitr?
body: <p>I'm writing my package's vignette and I'm trying include a paper containing multiple authors as reference, using something like this in the beginning of the code:</p>
  
  <pre><code>---
  references:
  - id: doe2009
    title: A Method for Something
    author:
    - family: Doe
      given: John
    - family: Shepard
      given: Jane
    container-title: Some Journal
    volume: 11
    issue: 45
    page: 33-39
    type: article-journal
    issued:
      year: 2009
  ---
  </code></pre>
  
  <p>Problem is, my citation goes on the end like this:</p>
  
  <p>Doe, John, and Jane Shepard. 2009. “A Method for Something.” Some Journal 11 (45): 33–39.</p>
  
  <p>There is one pattern for the first author and another for the second author.</p>
  
  <p>How can I change this to a more consistent form? Also, I'm trying to avoid external files to my package... is there a way for doing this without using an external csl?</p>
  
  <p>I'm sorry that the problem may sound trivial. I don't know nothing about CSL and this is my first attempt to publish a package.</p>
