1.从一个简单的boxplot开始

rm(list = ls())    #清空所有环境变量
if(!require(ggplot2))install.packages('ggplot2')  #条件安装ggplot2
library(ggplot2)      #加载ggplot2
ggplot(iris,aes(x =  Species,y = Sepal.Length, fill = Species))+
  geom_boxplot()    #利用内置数据集iris

2.利用theme_set()修改

theme_set(theme_classic())
ggplot(iris,aes(x =  Species,y = Sepal.Length, fill = Species))+
  geom_boxplot()

3.利用labs()修改

ggplot(iris,aes(x =  Species,y = Sepal.Length, fill = Species))+
  geom_boxplot()+
  labs(title = 'title from labs',subtitle = 'subtitle from labs',x ='',y='',caption = 'caption from labs')

4.利用theme()修改

ggplot(iris,aes(x =  Species,y = Sepal.Length, fill = Species))+
  geom_boxplot()+
  labs(title = 'title from labs',subtitle = 'subtitle from labs',x =NULL,y=NULL,caption = 'caption from labs')+
  theme(legend.position = 'None')

ggplot(iris,aes(x =  Species,y = Sepal.Length, fill = Species))+
  geom_boxplot()+
  labs(title = 'title from labs',subtitle = 'subtitle from labs',x ='',y='',caption = 'caption from labs')+
  theme(axis.text.x = element_text(angle=65, vjust=0.6))

+ coord_polar() #转换为极坐标
+ coord_flip()  #交换X轴和Y轴
