First slide

{.incremental} fenced div 👍
from: markdown+emoji in header allows emoji usage 😄
Chunk options are hashpipe, completion works great 👋
Great trick in RStudio: CTRL+, ✔️

echo: fenced ideal for teaching

Fragment for increment

```{r}
#| output-location: column-fragment
1 + 3
mean(c(1, 3, 6))
```

[1] 4
[1] 3.333333

Click logo

Following discussion on quarto-cli, logo on each slide can point to the desired URL.

Set it in the YAML header with logo_url: "https://fasterthanli.me"

If not set, it points to https://quarto.org

Practical

Using {background="#e4f0ff"} class to the header2

Absolute positioning of image and text, increment with . . .

Console

Columns as fenced divs `{.columns}` and LaTex

\[\begin{gather*} a_1=b_1+c_1\\ a_2=b_2+c_2-d_2+e_2 \end{gather*}\]

Playing with {.fragment} transitions

Layout for images

Two ways of installing packages

`.r-fit-text` class

Big Text

Blockquote

Literate programming is the practice of mixing code and descriptive writing in order to execute and explain a data analysis simultaneously in the same document.

— William Landau

Layout for chunks too

Highlight code lines, incremental with |
Execute code inside a caption with !expr

```{r}
#| layout-ncol: 2
#| code-line-numbers: "|3-4,6|7"
#| fig-cap: !expr glue::glue("Swiss data are {nrow(swiss)} rows")
#| fig-height: 3
plot(swiss$Agriculture, swiss$Fertility)
plot(swiss$Agriculture, swiss$Education)
```
