关键在于参数outlier.alpha,将其设置为数值“0”就可以了,只是隐藏并未去除。 library(ggplot2)element<-sample(letters[1:3],1e3,replace=T)value<-rnorm(1e3)df<-data.frame(element,value)head(df)ggplot(df,aes(x=element,y=value,color=element))+geom_boxplot(outlier.colour="red",outlier.shape=7)...

Figure 1: ggplot2 Boxplot with Outliers.As you can see based on Figure 1, we created a ggplot2 boxplot with outliers. Now, let’s remove these outliers…Example: Remove Outliers from ggplot2 BoxplotIf we want to remove outliers in R, we have to set the outlier.shape argument to be ...
去掉原始数据中的outlier 调整xlim和ylim的范围，不显示outlier
