R语言学习第二天----R语言绘图

R语言基础绘图：

普通散点图

柱状图：

饼图：pie()

 Q-Q图

opar <- par(no,readonly=TRUE)

 plot(dose,drugA,type = "b")

par(lty=2,pch=17)

饼图：

pie(x,labels = )

par(mfrow=c(2,2)):将画图的区域分成4个模块

> par(mfrow=c(2,2))

> x <- c(10,12,4,16,8)

> lab <- c("US","UK","CHN","Ger","France")

> pie(x,lab,main="Simple Pie Chart")

pct <- round(x/sum(x)*100)  //求出比例

pie(x,lab,col=rainbow(length(lab)),main="Pie Chart With Percentage")  //添加颜色

library(plotrix)

pie3D(x,lab,explode=0.1，main="3D Pie Chart")

//画三维饼图

fan.plot(x,labels=lab,main="Fan Plot") //扇形饼图

直方图：

hist(x,breaks=12,col="red",xlab="Miles Per Callon")

hist(x,freq=FALSE,breaks=12,col="green",xlab="Mile Per Callon")

rug(jitter(x))

lines(density(x),col="red",lwd=2)

> par(mfrow=c(2,2))
> x <- c(10,12,4,16,8)
> lab <- c("US","UK","CHN","Ger","France")
> pie(x,lab,main="Simple Pie Chart")
> pct <- round(x/sum(x)*100)
> pct
[1] 20 24  8 32 16
> lab <- paste(lab," ",pct,"%",sep=" ")
> lab
[1] "US   20 %"
[2] "UK   24 %"
[3] "CHN   8 %"
[4] "Ger   32 %"
[5] "France   16 %"
> pie(x,lab,col=rainbow(length(lab)),main="Pie Chart With Percentage")
> library(Plotrix)

pie3D(x,explode=0.1,main="3D Pie Chart")
> fan.plot(x,labels=lab,main="Fan Plot")
