本文介绍如何使用R语言的pie()函数绘制基本饼图，并展示如何添加百分比标签、颜色以及创建3D饼图。此外，还介绍了如何使用plotrix包中的fan.plot()函数来绘制扇形图。

pie()

pie(x,labels)

x：非负数向量，表示面积

labels：各扇形标签的字符型向量

例

#如下图
par(mfrow=c(2,2))                             
slices <- c(10, 12,4, 16, 8) 
lbls <- c("US", "UK", "Australia", "Germany", "France")

pie(slices, labels = lbls, 
    main="Simple Pie Chart")

pct <- round(slices/sum(slices)*100)                      
lbls <- paste(lbls, pct) 
lbls <- paste(lbls,"%",sep="")
pie(slices,labels = lbls, col=rainbow(length(lbls)),
    main="Pie Chart with Percentages")

library(plotrix)                                               
pie3D(slices, labels=lbls,explode=0.1,
      main="3D Pie Chart ")

mytable <- table(state.region)                                   
lbls <- paste(names(mytable), "\n", mytable, sep="")
pie(mytable, labels = lbls, 
    main="Pie Chart from a dataframe\n (with sample sizes)")

par(opar)

扇形图

#如下图
library(plotrix)
slices <- c(10, 12,4, 16, 8) 
lbls <- c("US", "UK", "Australia", "Germany", "France")   
fan.plot(slices, labels = lbls, main="Fan Plot")
