scale_duke_color_discrete()

This vignette is intended to demonstrate the functionality of scale_duke_color_discrete(). The function allows users to utilize a discrete color scale of Duke official branding colors on ggplot2 visualizations. It is fully integrated with ggplot2 visualizations.

Plot Examples

For these visualizations, we will use the penguins dataset from the palmerpenguins package.

library(palmerpenguins)
library(duke)
library(ggplot2)
library(ggmosaic)

Scatter Plot

plot <- ggplot(penguins, aes(x = bill_length_mm, y = bill_depth_mm)) +
  geom_point(aes(color = species)) +
  labs(
    title = "Bill Length vs. Bill Depth", 
    caption = "(Colors used) \n Duke Royal Blue, Duke Navy Blue, Copper", 
    x = "Bill Length (mm)", 
    y = "Bill Depth (mm)"
  )

plot +
  scale_duke_color_discrete()

Jitter Plot

plot <- ggplot(penguins, aes(x = island, y = bill_depth_mm)) +
  geom_jitter(aes(color = species)) +
  labs(
    title = "Bill Length vs. Bill Depth", 
    caption = "(Colors used) \n Duke Royal Blue, Duke Navy Blue, Copper", 
    x = "Bill Length (mm)", 
    y = "Bill Depth (mm)"
  )
