最近は、箱ひげ図にデータをドットプロットするのを求められるようです。
定番の"iris"データを使って練習
ちなみにドットプロットは蜂群図というらしい

最後のところが重要
geom_beeswarmを使うとこんな感じ
install.packages("ggbeeswarm") #if you don't have installed package library(tidyverse) library(ggbeeswarm) p_length_bees <- p_length + geom_beeswarm(aes(color = Species)) p_length_bees
p_length_dot <- p_length + geom_point(position = position_jitter(width=0.05)) p_length_dot
