```

Here, we use the `penguins` dataset from the `{palmerpenguins}` package to 
provide simple examples of how gameR can be used to customize a plot using
either `{ggplot2}` or base R. We will plot a scatter plot of flipper length (in
mm) against body mass (in g) with the points colored by species.  

## Using `{ggplot2}`

To use palettes from gameR in ggplot, a palette can be specified via either
`scale_color_manual()` or `scale_fill_manual()` to adjust the color or fill
respectively. When specifying a palette, the `values =` argument must be used.
Calling the `scale_*` function will not allow a palette to be specified if
no named argument is used. 

```{R, warning = FALSE}
penguins %>%
  ggplot(aes(x = body_mass_g, y = flipper_length_mm, color = species)) +
  geom_point() +
  theme_bw() +
  ggtitle("ggplot example using the 'rayman' palette") +
  scale_color_manual(values = gameR_cols("rayman"))
```

## Using base R

If base R plotting is being used, the `bg` argument can be used to specify the
color of the points. Here we use `gameR_cols()` in combination with `unclasss()`
to color by species.   

```{R}
par(bg = "white")

attach(penguins)
plot(
  x = body_mass_g,
  y = flipper_length_mm,
  main = "Base R example using the 'cyberpunk' palette",
  cex = 1,
  pch = 21,
  bg = gameR_cols("cyberpunk")[unclass(species)]
)
legend(5500, 200,
  legend = attr(unclass(species), "levels"),
  fill = gameR_cols("cyberpunk"), cex = 0.8
)
```
