This vignette is intended to demonstrate the breadth of scale_duke_continuous() and its various applications. It is fully integrated with ggplot2 visualizations.

Plot Examples

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

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

Scatter Plots

plot <- ggplot2::ggplot(palmerpenguins::penguins, ggplot2::aes(bill_length_mm, flipper_length_mm)) +
  ggplot2::geom_point(ggplot2::aes(colour = bill_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)")
