3D pie chart:

> Library (Plotrix)
> Elem = C (' A ', ' B ', ' C ', ' d ', ' E ')
> num = C (12,32,14,42,20)
> numsum = SUM ( num)
> percent = Round (num/numsum*100,2)
> percent
[1] 10.00 26.67 11.67 35.00 16.67
> Percent = paste (percent, '% ', sep= ')
> Percent
[1] "Ten%"    "26.67%" "11.67    %" "16.67" "
  
   > pielabels = paste (elem,percent,sep= ' \ n ')
> Pie3d (num,main= ' My  3d-pie ', labels=pielabels,explode= 0.1,radius=0.8,height=0.1)
  

Note: the first thing to download is to install the Plotrix package. The round () function in percent = Round (num/numsum*100,2) is rounded and takes 2 decimal places, at which point the percent is the shaping vector. Percent = paste (percent, '% ', sep= ') in paste () is a string connection, and percent becomes a character vector after completion. Pie3d () Parameter:
Main: Pie chart main title. Labels: Tags for each "block". Explode: The interval between each "block", the default value is 0. Radius: The entire "pie" size, the default value is 1,0~1 to zoom out. Height: The width of the pie block, the default value is 0.1.
