scale_duke_fill_discrete() • duke

This vignette is intended to demonstrate the functionality of scale_duke_fill_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)

Bar Plot

plot <- ggplot(palmerpenguins::penguins, aes(x = species, fill = species)) +
  geom_bar() +
  labs(title = "Distribution of Species", caption = "(Colors used) \n Duke Royal Blue, Duke Navy Blue, Copper", x = "Species", y = "Count")

plot +
  scale_duke_fill_discrete()

Histogram Plot

plot2 <- ggplot(palmerpenguins::penguins, aes(x = bill_length_mm)) +
  geom_histogram(aes(fill = species)) +
  labs(title = "Distribution of Bill Length", caption = "(Colors used) \n Duke Royal Blue, Duke Navy Blue, Copper", x = "Bill Length (mm)", y = "Count")

plot2 +
  scale_duke_fill_discrete()
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
