ggplot2每个组只包含一个观察值 [英] ggplot2 each group consists of only one observation

问题描述

我试图用ggplot2绘制图表

所以我有以下数据框：

 iter se perf name 
 1 V1 0.6463573 12.8 e 
 2 V2 0.3265986 16.8 e 
 3 V3 0.2333333 19.1 e 
 4 V4 0.1000000 19.9 e 
 5 V5 0.0000000 20.0 e 
 6 V1 0.7483315 12.6 f 
 7 V2 0.6333333 16.3 f 
 8 V3 0.6798693 18.8 f 
 9 V4 0.2236068 19.5 f 
 10 V5 0.1000000 19.9 f 
  

我试图用类似于 page （在曲线图下）。

<所以这里是绘图的代码：

  pd < -  position_dodge（.1）
 ggplot（df ，aes（x = iter，y = perf，color = name））+ 
 geom_errorbar（aes（ymin = perf-se，ymax = perf + se），width = .1，position = pd）+ 
 geom_line（position = pd）+ 
 geom_point（位置= pd）+ 
 ylim（0，20）
  

group = 1 或 group = name 但它没有帮助。

我也收到以下警告：

  ymax未定义：调整使用y来代替
 ymax未定义的位置：使用y调整位置
 geom_path：每个组只包含一个观察值。你需要调整团体审美吗？ 
  

在互联网上查看后，我发现前两个是由position_dodge引起的，但我认为它是因为ggplot，第三个实际上是因为我的断开点。

任何想法如何连接它们？

  geom_line（ position = pd）
  

by

  geom_line（position = pd，aes（group = name））
  

I am trying to plot the graph using ggplot2

So I have the following dataframe:

   iter        se perf name
1    V1 0.6463573 12.8    e
2    V2 0.3265986 16.8    e
3    V3 0.2333333 19.1    e
4    V4 0.1000000 19.9    e
5    V5 0.0000000 20.0    e
6    V1 0.7483315 12.6    f
7    V2 0.6333333 16.3    f
8    V3 0.6798693 18.8    f
9    V4 0.2236068 19.5    f
10   V5 0.1000000 19.9    f

and I am trying to plot it in the format similar to this page (under Line graphs).

So here is the code for plotting:

pd <- position_dodge(.1)
ggplot(df, aes(x=iter, y=perf, colour=name)) + 
  geom_errorbar(aes(ymin=perf-se, ymax=perf+se), width=.1, position=pd) +
  geom_line(position=pd) +
  geom_point(position=pd)+
  ylim(0, 20)

and it is working nicely: , except that I want these dots to be connected. I tried to add group=1 or group=name to this part aes(x=iter, y=perf, colour=name) but it did not help.

I also get these warnings:

ymax not defined: adjusting position using y instead
ymax not defined: adjusting position using y instead
geom_path: Each group consist of only one observation. Do you need to adjust the group aesthetic?

After looking in the internet, I found that the first two are due to position_dodge, but I think it is because of the ggplot, the third one is actually because of my disconnected points.

Any ideas how to connect them?

解决方案

You need to adjust the group aesthetic, replace :

   geom_line(position=pd) 

by

  geom_line(position=pd,aes(group=name))
