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)
