Apply Microsoft Themed Colour Scales and Aesthetics to ggplot2 Plots

This function provides a convenient way to apply Microsoft themed colour scales and aesthetics to ggplot2 plots. The user can specify whether they want a continuous or discrete theme by providing the scale_type argument.

Usage

dr_theme_microsoft(
  scale_type = c("discrete", "continuous"),
  index = NULL,
  direction = c("forwards", "backwards"),
  guide = "colourbar",
  fallback_font = "sans"
)

Arguments

scale_type: A character string specifying the type of scale, either "continuous" or "discrete". Default is "discrete". Simply, is the data mapped to the colour or fill aesthetic discrete or continuous.
index: An optional numeric index or vector of indices to select specific colours from the Microsoft colour palette.
direction: A character string, either "forwards" or "backwards" specifying the direction of the colour or fill gradient for continuous scales. Default is "forwards".
guide: An optional character string specifying the type of guide to use for continuous scales. Default is "colourbar", but other values include "legend", and "none". A rule of thumb is if the data are continuous, "colourbar" should be used, and if the data are discrete then "legend" should be used.
fallback_font: Adds a fallback font of 'sans' in case user does not have required font (Segoe UI).

Value

A list containing the ggplot2 theme, fill scale, and colour scale.

Examples

# \donttest{
library(ggplot2)

# Example with continuous theme
ggplot(mtcars, aes(x = wt, y = mpg, colour = qsec)) +
  geom_point() +
  dr_theme_microsoft(scale_type = "continuous")


# Example with discrete theme
ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, colour = Species)) +
  geom_point() +
  dr_theme_microsoft(scale_type = "discrete")

  # }
