## Meet the penguins

The `penguins` data contains size measurements for 
penguins from three islands in the Palmer Archipelago, 
Antarctica.

The three species of penguins have quite distinct 
distributions of physical dimensions (@fig-penguins).

```{r}
#| label: fig-penguins
#| fig-cap: "Dimensions of penguins across three species."
#| warning: false
library(tidyverse, quietly = TRUE)
library(palmerpenguins)

  geom_point(aes(color = species)) +
  scale_color_manual(
    values = c("darkorange", "purple", "cyan4")) +
  theme_minimal()
```

  ## Meet the penguins
  
  The `penguins` data contains size measurements for 
  penguins from three islands in the Palmer Archipelago, 
  Antarctica.
  
  The three species of penguins have quite distinct 
  distributions of physical dimensions (@fig-penguins).

• Include code. R, Python, Julia, Observable, or any language with a Jupyter kernel.

  ```{r}

Use a tool with a rich authoring experience

RStudio,
Positron with bundled Quarto extension, or
Visual Studio Code + Quarto extension

• Run code cells as you write

• Render with a button or keyboard shortcut

• Edit Quarto documents with a Visual Editor

  

  • Apply formatting in Visual Editor. Saved as Markdown in source.

  • Insert elements like code cells, cross references, and more.

Or any text editor

Quarto documents (.qmd) can be edited in any tool that edits text.

Render

Save, then render to preview the document output.

Terminal

quarto preview hello.qmd

RStudio: Use Render button

Positron and VS Code: Use Preview button

The resulting HTML/PDF/MS Word/etc. document will be created and saved in the same directory as the source .qmd file.

Rendered output: hello.html

Highlights in the rendered output

• Features for scientific publishing. Cross references, citations, equations, and more.

• Output integrated into document. Control how output appears with special comments in your code.

Behind the Scenes

When you render a document, Quarto:

1. Runs the code and embeds results and text into an .md file with:
   • Knitr, if any {r} cells, or
   • Jupyter, if any other cells.
2. Converts the .md file into the output format with Pandoc.

Publish

Terminal

quarto publish {venue} hello.qmd

{venue}: quarto-pub, connect, gh-pages, netlify, confluence

• Quarto Pub Free publishing service for Quarto content.

• Posit Connect Org-hosted, control access, schedule updates.
  RStudio: Use Publish button
  Positron and VS Code: Use Posit Publisher extension.

Quarto Projects

Create websites, books and more

A directory of Quarto documents + a configuration file (_quarto.yml)

See examples at: https://quarto.org/docs/gallery/

Get started from the command line:

Terminal

quarto create project {type}

{type}: default, website, blog, book, confluence, manuscript

RStudio: Use File > New Project
Positron and VS Code: Use Quarto: Create Project command

Include Code

Code Cells

Code cells start with ```{language}, and end with ```.

RStudio, Positron & VS Code: Use Insert Code Chunk/Cell.

```{r}
#| label: chunk-id
```

```{python}
#| label: chunk-id
```

Other languages: {julia}, {ojs}

Add code cell options with #| comments.

Cell options control execution, figures, tables, layout and more. See them all at: https://quarto.org/docs/reference/cells/

Execution Options

Option	Default	Effects
echo	true	false: hide code in output fenced: include code cell syntax
eval	true	false: don’t run code
include	true	false: don’t include code or results
output	true	false: don’t include results asis: treat results as raw markdown
warning	true	false: don’t include warnings in output
error	false	true: include error in output and continue with render

Set execution options at the cell level:

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

```{python}
#| echo: false
```

Set options in code cells with #| comments and YAML syntax: key: value.

Or globally in the YAML header with the execute option:

---
execute:
  echo: false
---

Inline Code

Use computed values directly in text sections. Code is evaluated at render and results appear as text.

Knitr

Value is `r 2 + 2`.

Jupyter

Value is `{python} 2 + 2`.

Output

Value is 4.

Markdown

|object | radius|
|:------|------:|
|Sun    | 696000|
|Earth  |   6371|

: CAPTION {#tbl-LABEL}

Computation

Output a markdown table or an HTML table from your code.

Knitr

Use knitr::kable() to produce markdown:

```{r}
#| label: tbl-LABEL
#| tbl-cap: CAPTION

knitr::kable(head(cars))
```

Also see the R packages: gt, flextable, kableExtra.

Jupyter

Add Markdown() to Markdown output:

```{python}
#| label: tbl-LABEL
#| tbl-cap: CAPTION
import pandas as pd, tabulate
from IPython.display import Markdown
df = pd.DataFrame({"A": [1, 2], 
                   "B": [1, 2]})
Markdown(df.to_markdown(index=False))
```

Cross References

1. Add labels:

   • Code cell: add option label: prefix-LABEL
   • Markdown: add attribute #prefix-LABEL

2. Add references: @prefix-LABEL, e.g.

   You can see in @fig-scatterplot, that...

prefix	Renders
fig-	Figure 1
tbl-	Table 1
eq-	Equation 1
sec-	Section 1

Citations

1. Add bibliography file to the YAML header:

   ---
   bibliography: references.bib
   ---

2. Add citations: [@citation], or @citation

RStudio, Positron & VS Code: Use Insert Citations dialog in the Visual Editor. Build your bibliography file from your Zotero library, DOI, Crossref, DataCite, or PubMed.
