ggpie繪制餅圖

【R畫圖學習16.3】餅圖3--ggpie

基本的餅圖

## 使用diamonds數(shù)據(jù)集
head(diamonds)

## 基本的餅圖
ggpie::ggpie(data = diamonds, group_key = "cut", 
      count_type = "full", ## 設置未count時需要有名字為count的列（數(shù)值型） 
      label_info = "all", # 標簽內(nèi)容：默認"count", "ratio", "all"
      label_type = "horizon", # 標簽形式："none", "circle", "horizon"
      label_split = NULL,
      label_size = 4,
      label_pos = "in",# 超過閾值的標簽在內(nèi)部
      label_threshold = 25) # 設置閾值

中間為空心的餅圖

## 中間為空心的餅圖
ggdonut(data = diamonds, group_key = "cut", count_type = "full",
        label_info = "all",
        label_type = "circle",
        label_split = NULL,
        label_size = 4,
        label_pos = "in")

中間有兩個圈的餅圖

ggnestedpie(data = diamonds, group_key = c("cut", "color"), count_type = "full",
            inner_label_info = "all",
            inner_label_split = NULL,
            inner_label_threshold = 3,# 設置內(nèi)層環(huán)形的閾值
            inner_label_size = 2,
            outer_label_type = "circle", # 設置外層環(huán)形
            outer_label_pos = "in",

小遺憾，沒有參數(shù)可以顯示每個部分對應的名稱，如Ideal、Good等

繪圖很方便，還可以直接計算比例并標注
