本文介绍了ggplot2在箱形图上添加文本的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我有一个数据,我正在将 ggplot2 作为箱形图绘制,看起来像 >头(varf) sID变量值 1 SP_SA036,SA040 CM0001 0.492537313 2 SP_SA036,SA040 CM0001 0.479564033 3 SP_SA036,SA040 CM0001 0.559139785 4 SP_SA036,SA040 CM0001 0.526806527 5 SP_SA036,SA040 CM0001 0.009049774 6 SP_SA036,SA040 CM0001 0.451612903 变量列包含16个不同的ID(从CM0001到CM0016) 我有一个带注释的数据框 类别注释 CM001 HG4450 CM002 HG3288 .. CM016 MM8998 我想将这些注释映射到我的箱子图上,但是找不到这样做的方法,在boxplot中使用geom_text的正确语法是什么? 谢谢 解决方案 有很多方法可以解决这个问题,例如这里和此处。可能最简单的方式是 pre code> meds ggplot(mtcars,aes(factor(cyl),mpg))+ geom_boxplot()+ geom_text(data = data.frame(),aes(x = names(meds),y = meds,label = 1:3),col ='red',size = 10) I have a data that I'm plotting on ggplot2 as boxplots which look like > head(varf) sID variable value1 SP_SA036,SA040 CM0001 0.4925373132 SP_SA036,SA040 CM0001 0.4795640333 SP_SA036,SA040 CM0001 0.5591397854 SP_SA036,SA040 CM0001 0.5268065275 SP_SA036,SA040 CM0001 0.0090497746 SP_SA036,SA040 CM0001 0.451612903The variable column contains 16 different IDs (from CM0001 to CM0016)I have a dataframe with annotation category annotationCM001 HG4450CM002 HG3288..CM016 MM8998I would like to map these annotations on top of my boxplots but couldn't find a way to do it, what is the right syntax of using geom_text with boxplot ?Thanks 解决方案 There are many ways to approach this problem, e.g. here and here. Probably the simplest way is meds <- c(by(mtcars$mpg, mtcars$cyl, median))ggplot(mtcars, aes(factor(cyl), mpg)) + geom_boxplot() + geom_text(data=data.frame(), aes(x=names(meds), y=meds, label=1:3), col='red', size=10) 这篇关于ggplot2在箱形图上添加文本的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
