Warwick-branded plots, presentations and websites using Quarto and R

warwickplots

An R package with colour palettes and a ggplot2 theme that are consistent with The University of Warwick’s branding, especially its colours and typography.

The palettes are built using the palettes package. The ggplot2 theme is heavily inspired by the work of Cara Thompson, particularly her talk on applying a unifying aesthetic to your plots.

The palettes

library(warwickplots)
plot(warwick_palettes)

warwickplots and ggplot2

Colour and fill scales provided by the palettes package

scale_colour_palette_d() scale_colour_palette_c() scale_colour_palette_b()

scale_fill_palette_d() scale_fill_palette_c() scale_fill_palette_b()

theme_warwick()

`theme_warwick()`

An extension of ggplot2::theme_minimal(), offering the following in addition:

Text hierarchy, with different sizes and colours
Spacing, giving the text room to breathe
Uses element_textbox_simple() from ggtext for the plot title and subtitle, to enable use of markdown and CSS styling, and text-wrapping if the title/subtitle is long
Places the legend above the plot
Uses Lato or Avenir Next font (for online or print use respectively), if your system is set up for it
