问题 do you have any idea of how to apply jittering just to the outliers data of a boxplot? This is the code: ggplot(data = a, aes(x = "", y = a$V8)) + geom_boxplot(outlier.size = 0.5)+ geom_point(data=a, aes(x="", y=a$V8[54]), colour="red", size=3) + theme_bw()+ coord_flip() thank you!! 回答1: Added a vector to your data set to indicate which points are and are not outliers. Then, Set the geom_boxplot to not plot any outliers and use a geom_point to plot the outliers explicity. I will use the
