A 'ggplot2' Extension Inspired by 'GraphPad Prism'

Provides various themes, palettes, and other functions that are used to customise ggplots to look like they were made in 'GraphPad Prism'. The 'Prism'-look is achieved with theme_prism() and scale_fill|colour_prism(), axes can be changed with custom guides like guide_prism_minor(), and significance indicators added with add_pvalue().

ggprism

The ggprism package provides various themes, palettes, and other useful functions to customise ggplots and give them the ‘GraphPad Prism’ look.

How to Use

See the Getting Started page for a quick overview of ggprism features. Detailed examples and instructions can be found below and on the ggprism website.

library(ggplot2)
library(ggprism)

tg <- ToothGrowth
tg$dose <- as.factor(tg$dose)

base <- ggplot(tg, aes(x = dose, y = len)) + 
  geom_violin(aes(colour = dose, fill = dose), trim = FALSE) + 
  geom_boxplot(aes(fill = dose), width = 0.2, colour = "black") + 
  scale_y_continuous(limits = c(-5, 40))

p_vals <- tibble::tribble(
  ~group1, ~group2, ~p.adj,   ~y.position,
  "0.5",   "1",     8.80e-14, 35,
  "0.5",   "2",     1.27e-7,  39
)

base

base + 
  scale_color_prism("floral") + 
  scale_fill_prism("floral") + 
  guides(y = "prism_offset_minor") + 
  theme_prism(base_size = 16) + 
  theme(legend.position = "none") + 
  add_pvalue(p_vals, label = "p = {p.adj}", tip.length = 0, label.size = 4)
