# grab the radial positions of the labels

# labels设置每个分饼的标题

# main 设置整个3D饼图的标题

lp<-pie3D(pieval,radius=0.8,labels=pielabels,explode=0.1,main="3DPIE OPINIONS")

# radius 设置半径，主要是饼图区域半径占整个绘图区域半径的比例

#,explode=0.1 设置分饼之间分离程度

pielabels[4]<-"We cannot survivewithout our pies"

lp[4]<-4.8

# specify some new colors

    col=c("brown","#ddaa00","pink","#dd00dd"),labelpos=lp)

#col 设置颜色，注意顺序
