pie 饼状图

pie（百分比，标注文字，main=“标题文字”，颜色）

x <- c(1,2,3,4,5)
> a <- c("a","b","c","d","e")
> pct2 <- round(x/sum(x)*100)
> b <- paste(a,pct2,"%")
> pie(x,labels = b,radius = 0.5，col=rainbow(length(b)))

　　

fan.plot 扇形图

x <- c(1,2,3,4,5)
> a <- c("a","b","c","d","e")
> pct2 <- round(x/sum(x)*100)
> b <- paste(a,pct2,"%")
> pie(x,labels = b,radius = 0.5，col=rainbow(length(b)))

hist 直方图

hist(mtcars$mpg,breaks = 15,freq = FALSE)

rug 轴须图

rug(jitter(mtcars$mpg))

用来表示密集程度的

lines(density(mtcars$mpg))

线段拟合，用来更缓和的说明问题
