• pie()

pie(x,labels)

x：非負數向量，表示面積

labels：各扇形標簽的字符型向量

例

#如下圖 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)
