如何在由highcharter制作的箱线图中添加均值? [英] How to add mean in a boxplot made with highcharter?

问题描述

我想在用{highcharter}表示的均值上加上方框图.默认情况下，它显示:最小值，最大值，Q1，Q3和中位数.

I would like to add on the boxplot made with {highcharter} the mean. By default, it displays : min, max, Q1, Q3 and median.

非常感谢！

library(dplyr)
library(highcharter) 

data(pokemon) 

dat <- data_to_boxplot(pokemon, height)

highchart() %>%
  hc_xAxis(type = "category") %>%
  hc_add_series_list(dat)

dat <- data_to_boxplot(pokemon, height, type_1, name = "height in meters")

highchart() %>%
  hc_xAxis(type = "category") %>%
  hc_add_series_list(dat)

推荐答案

您可以使用以下代码

library(dplyr)
library(highcharter) 

data(pokemon) 

dat <- data_to_boxplot(pokemon, height)

highchart() %>%
  hc_xAxis(type = "category") %>%
  hc_add_series_list(dat)

dat <- data_to_boxplot(pokemon, height, type_1, name = "height in meters")

my_data <- pokemon %>% 
  group_by(type_1) %>% 
  summarise(Mean = mean(height))

highchart() %>%
  hc_xAxis(type = "category") %>%
  hc_add_series_list(dat) %>%
  hc_add_series(name = "Mean",
    data = my_data,
    type = "scatter",
    hcaes(x = "type_1", y = "my_data$Mean")
  )
