向R中的箱线图添加统计信息表 [英] Adding a table of statistics to a boxplot in R

问题描述

我在同一个图形上创建了两个箱形图，如下所示。

I have created two boxplots on the same graph, as per code below

a = c(1,1,1,2,2,2,2,2,5,5,5,5,5,6,5,4,7)

b = c(1,1,2,2,2,2,2,2,5,5,5,5,5,6,5,3,8)

boxplot(  a
        , b
        , names = c("Category a", "Category b")
        , staplewex = 1 
        , horizontal = TRUE ) 

我还要添加重要数据点，Q1中位数等，作为标签或类似于图例的图形汇总表-这样可能吗？

I would like to also add the important data points, Q1 median etc, as labels or as a summary table on the graph similar to a legend - is this possible?

谢谢
