R语言ggplot2优雅的绘制环状云雨图

❝

本节来介绍如何使用「ggplot2」绘制环状云雨图，下面通过一个小栗子来进行介绍

❞

安装R包并加载

package.list=c("tidyverse","ggridges","extrafont","geomtextpath","gghalves","magrittr")

for (package in package.list) {
  if (!require(package,character.only=T, quietly=T)) {
    install.packages(package)
    library(package, character.only=T)
  }
}

加载数据

chocolate <- readr::read_csv('chocolate.txt')

数据清洗

char <- chocolate %>% select(most_memorable_characteristics, rating)
# 拆分数据
char_single <- char %>% 
  mutate(most_memorable_characteristics = strsplit(as.character(most_memorable_characteristics), ", ")) %>% 
  unnest(most_memorable_characteristics)  # 取消嵌套列表

char_single %<>% 
  group_by(most_memorable_characteristics) %>% 
  mutate(n = n(), 
         avg = mean
