EPI 590R - Quarto options

Chunk options

In your Quarto document, you had a chunk:

```{r}
#| echo: false
2 * 2
```

#| echo: false tells knitr not to show the code within that chunk

Some of the ones I find myself using most often:

#| eval: false: Don’t evaluate this chunk! Really helpful if you’re trying to isolate an error, or have a chunk that takes a long time
#| error: true: Render this even if the chunk causes an error
#| cache: true: Store the results of this chunk so that it doesn’t need to re-run every time, as long as there are no changes
#| warning: false: Don’t print warnings
#| message: false: Don’t print messages

You can tell the entire document not to evaluate or print code (so just include the text!) at the top:

---
title: "My document"
author: Louisa Smith
format: html
execute:
  eval: false
  echo: false
---

Careful! YAML is really picky about spacing.

There are lots of different options for the document

---
format:
  html:
    theme: yeti
---

Remember the pickiness: when you have a format option, html: moves to a new line and the options are indented 2 spaces

There’s an error in the code! Try to render it. Play around with eval: and error: chunk and document options to help you a) find the error and b) render the document despite the error. Then fix the error.
I don’t like the output from the first chunk, where the passages are loaded. Make it so that we don’t see this chunk’s code or output.
Play around with themes!
