R程序上的BoxPlot具有特定数据

问题描述

作为R的新手，我想到了一些问题。你们能帮我吗？

Being new to R, I have some problems in mind. Can you guys help me with it?

我有一系列数据

X     Gender     Score         Postal
1       F       427.395        123455
2       F       922.080        642362
3       M       114.500        123947 
4       M       176.345        236835
5       F       523.140        849729

以上是500个数据的样本。

Above is a sample of 500 data.

我希望分别对男女得分做一个箱形图。但是，邮政编码也会在箱线图中捕获。我该如何为boxplot创造条件，使其仅从X和Score中捕获按性别分类的数据？

I wish to do a boxplot on scores for females and males separately and also. However, there's the postal code which will be captured in the boxplot as well. How do I make the conditions for boxplot to capture data from only X and Score, classified by gender?

我试图在绘制boxplot之前先进行排序，但是可以吗？似乎没有用。你们对此有什么想法吗？

I have tried to do sorting first before plotting boxplot, but can't seem to make it work. Do you guys have any ideas on this?

谢谢！

推荐答案

调用数据 df ，使用：

boxplot(Score~Gender,data=df)

使用ggplot：

library(ggplot2)
ggplot(df) + geom_boxplot(aes(x=Gender, y=Score, color=Gender))
