scale_duke_continuous() • duke

This vignette is intended to demonstrate the breadth of scale_duke_continuous() and its various applications. Similar to the other existing color scale functions, this function can be applied to all ggplot2 visualizations.

For these visualizations, we will use the R dummy data set palmerpenguins.

library(duke)
library(palmerpenguins)
library(ggplot2)
attach(penguins)

plot <- ggplot2::ggplot(palmerpenguins::penguins, ggplot2::aes(bill_length_mm, flipper_length_mm)) +

  ggplot2::labs(title = "Bill Length vs. Flipper Length", caption = "There are three different species of penguins.", x = "Bill Length (mm)", y = "Flipper Length (mm)")
