QMD Essentials

Basic Document Structure

---
title: "Document Title"
author: "Author Name"
date: today
format: html
---

Content goes here.

A Quarto document consists of two main parts:

1. •YAML Front Matter: Metadata and configuration at the top, enclosed by ---.
2. •Markdown Content: Main body using standard markdown syntax.

Divs and Spans

Divs use fenced syntax with three colons:

::: {.class-name}
Content inside the div.
:::

Spans use bracketed syntax:

This is [important text]{.highlight}.

Details: references/divs-and-spans.md

Code Cell Options Syntax

A code cell starts with triple backticks and a language identifier between curly braces. Code cells are code blocks that can be executed to produce output.

Quarto uses the language's comment symbol + | for cell options. Options use dashes, not dots (e.g., fig-cap not fig.cap).

• •R, Python: #|
• •Mermaid: %%|
• •Graphviz/DOT: //|

```{r}
#| label: fig-example
#| echo: false
#| fig-cap: "A scatter plot example."
#| fig-width: 8
#| fig-height: 6

plot(x, y)
```

Common execution options:

Set document-level defaults in YAML front matter:

execute:
  echo: false
  warning: false

Details: references/code-cells.md

Cross-References

Labels must start with a type prefix. Reference with @:

• •Figure: fig- prefix, e.g., #| label: fig-plot → @fig-plot
• •Table: tbl- prefix, e.g., #| label: tbl-data → @tbl-data
• •Section: sec- prefix, e.g., {#sec-intro} → @sec-intro
• •Equation: eq- prefix, e.g., {#eq-model} → @eq-model

Example:

::: {#fig-plot}
A plot.

A caption for the plot.
:::

See @fig-plot for the results.

```{r}
#| label: fig-plot
#| fig-cap: "A caption for the plot."
plot(1)
```

See @fig-plot for the results.

Details: references/cross-references.md

Callout Blocks

Five types: note, warning, important, tip, caution.

::: {.callout-note}
This is a note callout.
:::

::: {.callout-warning}

## Custom Title

This is a warning with a custom title.

:::

Details: references/callouts.md

Figures

Basic figure with caption:

![Caption text](image.png){#fig-name fig-alt="Alt text"}

Subfigures:

::: {#fig-group layout-ncol=2}
![Sub caption 1](image1.png){#fig-sub1}

![Sub caption 2](image2.png){#fig-sub2}

Main caption for the group.
:::

Details: references/figures.md

Tables

Pipe table with caption:

::: {#tbl-example}

| Column 1 | Column 2 |
| -------- | -------- |
| Data 1   | Data 2   |

Table caption.
:::

Details: references/tables.md

Citations

Basic syntax:

According to @smith2020, the results show...
Multiple citations [@smith2020; @jones2021].
Parenthetical only [-@smith2020].

Configure in YAML:

bibliography: references.bib
csl: apa.csl

Details: references/citations.md

Common Workflows

Setting Up a Quarto Project

Create _quarto.yml in the project root:

project:
  type: website

website:
  title: "My Site"
  navbar:
    left:
      - href: index.qmd
        text: Home
      - href: about.qmd
        text: About

format:
  html:
    theme: cosmo
