title: Where is the Data Stored for Knitr Tables Generated in Bookdown?
body: <p>I am starting to write a simple book using Bookdown. I note that tables and figures can be generated using Knitr. However, I'm struggling to see where the data for a table or a figure is stored.</p>
  <p>The example provided at: <a href="https://bookdown.org/yihui/bookdown/" rel="nofollow noreferrer">https://bookdown.org/yihui/bookdown/</a> uses the following code:</p>
  <pre><code>```{r nice-tab, tidy=FALSE}
  knitr::kable(
    head(iris, 20), caption = 'Here is a nice table!',
    booktabs = TRUE
  )
  ```
  </code></pre>
  <p>However, I don't see a file containing the data for the 'nice' table among the files that are part of the package (or, similarly, the images that are used for figures).</p>
  <p>I'd appreciate anybody who could point me in the right direction please.</p>
