You can retrieve palettes using various methods listed below. natparks.pals(name="DeathValley",n=7,type="discrete")
natparks.pals("Yellowstone", 5)
natparks.pals("Glacier",n=15,type="continuous")
natparks.pals("Arches",n=100)
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
