R中同一图形中的并排直方图? [英] Side by Side histograms in the Same Graph in R?

问题描述

这实际上应该非常简单，但是我很难找到解决该问题的方法.

This should actually be really simple but I'm having a really hard time finding a solution to this problem.

我在R中有两个非常简单的数值向量.我只是试图用它们绘制直方图.但是我希望它们在同一张图上.棘手的部分是R默认情况下会重叠这两个直方图.我希望这些垃圾箱可以并排放置，以便可以更好地可视化显示数据.

I have two very simple numeric vectors in R. I am simply trying to plot a histogram with them. However I would like them to be on the same graph. The tricky part is R overlaps these two histograms by default. I would like the bins to be simply side by side so I can get a better visual representation of the data.

基本上这就是我想做的

我一般对R语言和统计计算语言还是陌生的，因此，如果您能回答我这个令人沮丧的问题，我将不胜感激.

I am fairly new to R and statistical computing languages in general so I would appreciate it if you would answer my frustrating problem.

推荐答案

该示例来自使用plotrix程序包.在此处找到了代码.您首先需要安装该软件包，然后才能访问multihist函数:

The example comes from using the plotrixpackage. Code was found here. You will first need to install that package before you can access the multihist function:

#install.packages("plotrix")
require(plotrix)

l <- list(rnorm(50),rnorm(50,sd=2),rnorm(50,mean=3))
multhist(l)
