如何与R中的因素一起制作整体箱形图？ [英] How to make an overall boxplot alongside factors in R?

问题描述

我试图创建一个箱形图，显示变量的所有因素，以及样本大小，并且在图的末尾还需要将所有值合并为一个的总体箱形图。我使用下面这行代码来完成除了整体情节之外的所有事情：

I am trying to create a boxplot that shows all of the factors of a variable, along with sample size, and at eh end of the plot also want an overall boxplot that combines all of the values into one. I am using the following line of code to do everything except making the overall plot:

library(ggplot2) 
library(plyr)
xlabels <- ddply(extract8, .(Fuel), summarize, xlabels = paste(unique(Fuel), '\n(n = ', length(Fuel),')'))

ggplot(extract8, aes(x = Fuel, y = Exfiltration.Fraction.Percentage))+geom_boxplot()+
  stat_boxplot(geom='errorbar', linetype=1) + 
  geom_boxplot(fill="pink") + geom_hline(yintercept = 0.4) + 
  scale_x_discrete(labels = xlabels[['xlabels']]) + ggtitle("Exfiltration Fraction (%) by Fuel   Type")

不知道如何添加将所有因素合并为一个的boxplot。

Not sure on how to proceed regarding adding a boxplot that combines all of the factors into one.

推荐答案

这当然不是解决问题的最优雅的方式，但它起作用：

This is certainly not the most elegant way to solve it, but it works:

1. 将您的数据集复制到新对象中。


2. 在新对象中，将vari能够包含您想要的标签的因素，例如总计。 使用 rbind 来附加旧的和新的将对象结合到一起并将结果归因于新对象。
在 ggplot 中，用新对象替换旧对象。

1. Copy your dataset into a new object.
2. Within the new object, replace the content of the variable containing the factors with the label you would like, for instance, "Total".
3. Use rbind to attach the old and new objects together and attribute the result to the new object.
4. In ggplot replace the old object by the new object.

我有同样的问题，无法找到答案并以此方式进行。

I had the same issue, couldn't find an answer and proceeded this way.
