knitr::opts_chunk$set(echo = TRUE)当堂作业boxplot
run一下这三个代码看一下区别
library(ggplot2)
ggplot(data = iris)+
geom_boxplot(mapping = aes(x = Species, y = Sepal.Width, color = Species))ggplot(data = iris)+
geom_boxplot(mapping = aes(x = Species, y = Sepal.Width, color = Species, fill = Species))ggplot(data = iris)+
geom_boxplot(mapping = aes(x = Species, y = Sepal.Width, fill = Species))boxplot线默认就是黑色的，如果改填充色直接改fill就好了
图层的叠放顺序和代码存在关联，最后一行代码在最上面的图层
思路：先排框架 “+”用来分隔函数（或者理解为分隔图层）
#局部分别设置
ggplot(data = iris)+
geom_violin(mapping = aes(x = Sepal.Width, y = Species, fill = Species))+
geom_boxplot(mapping = aes(x = Sepal.Width, y = Species))+
geom_jitter(mapping = aes(x = Sepal.Width, y = Species, shape = Species))#先全局后局部
ggplot(data = iris, mapping = aes(x = Sepal.Width, y = Species))+
geom_violin(mapping = aes(fill = Species))+
geom_boxplot()+
geom_jitter(mapping = aes(shape = Species))#单个图层手动修改指定
ggplot(data = iris, mapping = aes(x = Sepal.Width, y = Species))+
geom_violin(mapping = aes(fill = Species))+
geom_boxplot()+
geom_jitter(mapping = aes(shape = Species))+
scale_shape_manual(values = c(1,5,8))ggpubr中comparison的传递要求是列表，格式要求严格
好像上课的时候有点啥疑问但是又忘了 最近正好做到这里，实践的时候再看
