ggprism学习

ggprism包提供了各种主题、调色板和其他有用的函数来定制ggplot，并为它们提供GraphPad Prism外观。

install ggprism

install.packages("ggprism")

或者

remotes::install_github("csdaw/ggprism")

Example

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))
base

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 + 
  scale_color_prism("floral") +   #可以设置“candy_bright”
  scale_fill_prism("floral") + 
  guides(y = "prism_offset_minor") + 
  theme_prism(base_size = 16) + 
  theme(legend.position = "none") +  #可以调整legend的位置
  add_pvalue(p_vals, label = "p = {p.adj}", tip.length = 0, label.size = 4)

可以参考上述链接去实现该图。

附加

base <- ggplot(mpg, aes(x = as.factor(cyl), y = hwy)) +
geom_jitter(width = 0.2) +
theme(axis.line = element_line(colour = "black"))+scale_x_discrete(guide = guide_prism_bracket(width = 0.12, outside = FALSE)) +
theme(axis.line.x = element_line(colour = "red"),
axis.ticks.x = element_line(colour = "blue"),
axis.text.x = element_text(colour = "green"))
pp<-base +labs(x=" ",y="hwy")+theme(axis.text.y =element_text (color="black"),panel.background = element_blank())
