[轉] R 繪圖ggplot2 一頁多圖及子圖嵌入主圖的多種實現方法

一、一面多圖的實現方法:

- 輸入:

minute <- c(110,118,120,123,131,137,144,149,152,160)
VC <- c(5283,5299,5358,5292,5602,6014,5830,6102,6075,6411)
lrdata <- data.frame(minute,VC)
modelle <- lm(VC~minute,data=lrdata)
pre <- predict(modelle,newdata=data.frame(minute),interval = "prediction")
newlr <- cbind(lrdata,pre)

p1<-ggplot(newlr,aes(x=minute,y=VC))+geom_point(size=3,colour="blue")

p2<-ggplot(newlr,aes(x=minute,y=VC))+geom_point(size=3,colour="blue")+
geom_segment(aes(x=minute, xend=minute, y=VC, yend=fit),size=1,linetype=2,colour="red")+
geom_line(aes(y=fit), color = "blue", linetype = "dashed",size=1)

方法1:

- 輸入:

library(gridExtra)
grid.arrange(p1,p2,nrow=1)

- 結果:


方法2:

- 輸入:

library(Rmisc)
multiplot(p1,p2,cols=2)

- 結果:


方法3:

- 輸入:

install.packages("cowplot")
library(cowplot)
plot_grid(p1,  NULL, NULL,p2, labels = c("A", "", "", "B"),ncol = 2)

- 結果:

二、子圖嵌入主圖的實現方法:

方法1:

- 輸入:

library(grid)
vp <- viewport(width = 0.3, height = 0.4, x = 0.65,y = 0.9,just=c("left","top"))
   

# width\height表示插入圖形的大小,x\y表示插入圖形相對於圖片底層just的位置
print(p1)
print(p2,vp=vp)

- 結果:


方法2:

- 輸入:

install.packages("viridis")
library(
viridis)
ggdraw() +draw_plot(p1,0,0,1,1)+
draw_plot(p2,0.1,0.5,0.3,0.4)
   
# 0.1\0.5為圖的左下角x\y的位置,0.3\0.4為圖形的寬度和高度

- 結果:
