## This example

This example code mostly from the Quatro guide: https://quarto.org/docs/guide/ . GPL-2.

Quarto is very similar to R markdown, but also allows (inline) code blocks in Python, Julia, and Observable JS.

## Meet the penguins

The `penguins` data from the [**palmerpenguins**](https://allisonhorst.github.io/palmerpenguins "palmerpenguins R package") package contains size measurements for `{r} nrow(penguins)` penguins from three species observed on three islands in the Palmer Archipelago, Antarctica.

The plot below shows the relationship between flipper and bill lengths of these penguins.

```{r}
#| label: plot-penguins
#| warning: false
#| echo: false
# NOTE: We may want to add some sort of ighlighting for the above rendering options

ggplot(penguins, 
       aes(x = flipper_length_mm, y = bill_length_mm)) +
  geom_point(aes(color = species, shape = species)) +
  scale_color_manual(values = c("darkorange","purple","cyan4")) +
  labs(
    title = "Flipper and bill length",
    subtitle = "Dimensions for penguins at Palmer Station LTER",
    x = "Flipper length (mm)", y = "Bill length (mm)",
    color = "Penguin species", shape = "Penguin species"
  ) +
