ggplot2 Examples

Here are also some ways you can incorporate this package into {ggplot2}

ggplot(data=iris, aes(x=Species, y=Petal.Length, fill=Species)) +
  geom_violin() +
  scale_fill_manual(values=natparks.pals("Yellowstone", 3))

ggplot(data=iris, aes(x=Sepal.Length, y=Sepal.Width, color=Species)) +
  geom_point(size=2) +
  scale_color_manual(values=natparks.pals("Banff", 3))

ggplot(data=iris, aes(x=Species, y=Sepal.Width, color=Sepal.Width)) +
  geom_point(size=3) +
  scale_color_gradientn(colors=natparks.pals("Arches2"))

Colorblind Friendly checking

The colorblind friendliness of all palettes have been checked using colorblindcheck. Those with [min_dist] >10 for all color vision deficiencies - deuteranopia, protanopia, and tritanopia - are considered colorblind friendly. You can list the colorblind-friendly palettes with the following code:

NatParksPalettes::colorblind_palettes
[1] "Acadia"      "Arches"      "Arches2"     "DeathValley" "Glacier"     "KingsCanyon"

You can also check if a specific palette is colorblind friendly using the function provided

NatParksPalettes::colorblind.friendly("DeathValley")
[1] TRUE
