绘图布局
一、mfrow布局#mfrow或者mfcol
par('mfrow')
par('mfcol')
opar <- par(no.readonly = TRUE)#将可以修改的变量储存起来
par(mfrow=c(2,2))
par('mfrow')
plot(pressure,col="red",main="Pic 1")
barplot(table(mtcars$cyl),col = c("red","cyan","orange"),main = "Pic 2")
hist(rivers,breaks = 30,col = "pink",main = "Pic 3")
pie(c(1,3,4,2),labels = c("A","B","C","D"),main = "Pic 4")
par(mfrow=c(2,2))
layout.show(4)
par(mfcol=c(2,2))
layout.show(4)#与上面的不同，1234摆放位置不同
par(mfrow=c(1,2))#1行2列
barplot(1:6)
pie(1:6)
par(mfrow=c(2,1))#2行1列
barplot(1:6)
hist(rivers)
par(mfrow=c(2,3))#2行3列
layout.show(6)
hist(rivers)
hist(rivers)
hist(rivers)
hist(rivers)
hist(rivers)
hist(rivers)
par(mfrow=c(2,1))#2行1列
hist(rivers)
barplot(1:6)
#想让上下两张图离得近些
layout.show(2)
par('mar')
par(opar)
# 5.1 4.1 4.1 2.1
par(mfrow=c(2,1))#2行1列
par(mar=c(5.1,4.1,4.1,2.1))
hist(rivers)
par(mar=c(5.1,4.1,0,2.1))
barplot(1:6)#画图前调整下左上右
par(mfrow=c(2,2))#2行2列
layout.show(4)
par('mar')
par(mar=c(0,4.1,4.1,2.1))
hist(rivers)#贴着下边
par(mar=c(5.1,0,4.1,2.1))
barplot(1:6)#贴着左边
par(mar=c(5.1,4.1,0,2.1))
hist(rivers)#贴着上边
par(mar=c(5.1,4.1,4.1,0))
hist(rivers)#贴着右边
#以上都是规整的布局
2行2列
1行2列
2行1列
二、layout 布局
layout(mat = matrix(c(1,2,3,4)))
layout.show(4)
layout(mat = matrix(c(1,2,3,4),nrow=2,byrow=T))
matrix(c(1,2,3,4),nrow=2)
matrix(c(1,2,3,4),nrow=2,byrow=T)#绘图位置不同
layout.show(4)
hist(rivers)
plot(women)
barplot(1:6)
pie(1:6)
matrix(c(1,1,2,3),nrow=2,byrow=T)
layout(mat = matrix(c(1,1,2,3),nrow=2,byrow=T))
layout.show(3)
hist(rivers)
plot(women)
barplot(1:6)
matrix(c(1,2,1,3),nrow=2,byrow=T)
layout(mat = matrix(c(1,2,1,3),nrow=2,byrow=T))
layout.show(3)
hist(rivers)
plot(women)
barplot(1:6)
matrix(c(1,0,0,2,2,0,3,3,3),nrow=3,byrow=T)
layout(matrix(c(1,0,0,2,2,0,3,3,3),nrow=3,byrow=T))
layout.show(3)
hist(rivers)
plot(women)
barplot(1:6)
layout(matrix(c(1,1,2,3),nrow=2,byrow=T))
layout.show(3)
layout(matrix(c(1,1,2,3),nrow=2,byrow=T),width = c(2,1))
layout.show(3)
layout(matrix(c(1,1,2,3),nrow=2,byrow=T),width = c(2,1),heights = c(1,2))
layout.show(3)#调整组分高度和宽度
