问题描述
我正在测试以对数据集的情绪进行分析.在这里，我试图查看在消息量和嗡嗡声，消息量和得分之间是否有任何有趣的观察...
数据集如下所示:
>str(数据)'data.frame':40磅.11个变量中:$ Date Time:POSIXct，format:"2015-07-08 09:10:00""2015-07-08 09:10:00" ...$主题:chr"MMM""ACE""AES""AFL" ...$ Sscore:chr"-0.2280""-0.4415""1.9821""-2.9335" ...$ Smean:chr"0.2593""0.3521""0.0233""0.0035" ...$ Svscore:chr"-0.2795""-0.0374""1.1743""-0.2975" ...$分散:chr"0.375""0.500""1.000""1.000" ...$卷:num 8 4 1 1 5 3 2 1 1 2 ...$ Sbuzz:chr"0.6026""0.7200""1.9445""0.8321" ...$最后关闭:chr"155.430000000""104.460000000""13.200000000""61.960000000" ...$公司名称:chr"3M公司""ACE有限公司""AES公司""AFLAC Inc."...$ Date:日期，格式:"2015-07-08""2015-07-08" ... 我想到了线性回归，所以我想使用ggplot，但是我使用了这段代码，我认为我在某个地方出错了，因为我没有出现回归线...是因为回归是为了虚弱的?我提供了以下代码的帮助:.
这是我编写ggplot代码的方式:
库(ggplot2)要求(reshape2)data.2 =融化(data [3:9]，id.vars ='Svolume')ggplot(data.2)+aes(x =值，y =体积，颜色=变量)+geom_jitter()+geom_smooth(method = lm，se = FALSE，aes(group = 1))+facet_wrap(〜variable，scales ="free_x")+实验室(x =变量"，y =体积") I am testing to make an analysis of sentiment on a dataset. Here, I am trying to see if if there are any interesting observations between message volume and buzzs, message volume and scores...
There is what my dataset looks like:
> str(data)
'data.frame': 40 obs. of 11 variables:
$ Date Time : POSIXct, format: "2015-07-08 09:10:00" "2015-07-08 09:10:00" ...
$ Subject : chr "MMM" "ACE" "AES" "AFL" ...
$ Sscore : chr "-0.2280" "-0.4415" "1.9821" "-2.9335" ...
$ Smean : chr "0.2593" "0.3521" "0.0233" "0.0035" ...
$ Svscore : chr "-0.2795" "-0.0374" "1.1743" "-0.2975" ...
$ Sdispersion : chr "0.375" "0.500" "1.000" "1.000" ...
$ Svolume : num 8 4 1 1 5 3 2 1 1 2 ...
$ Sbuzz : chr "0.6026" "0.7200" "1.9445" "0.8321" ...
$ Last close : chr "155.430000000" "104.460000000" "13.200000000" "61.960000000" ...
$ Company name: chr "3M Company" "ACE Limited" "The AES Corporation" "AFLAC Inc." ...
$ Date : Date, format: "2015-07-08" "2015-07-08" ...
I thought about a linear regression, So I wanted to use ggplot, but I use this code and I think I got wrong somewhere as I don't have the regression lines that appears... Is it because the regression is to weak? I helped with the code from : code of topchef
Mine is:
library(ggplot2)
require(ggplot2)
library("reshape2")
require(reshape2)
data.2 = melt(data[3:9], id.vars='Svolume')
ggplot(data.2) +
geom_jitter(aes(value,Svolume, colour=variable),) + geom_smooth(aes(value,Svolume, colour=variable), method=lm, se=FALSE) +
facet_wrap(~variable, scales="free_x") +
labs(x = "Variables", y = "Svolumes")
But I probably missunderstood something as I don't get what I want.I am very new to R so I would love someone help me.
I have this error:
geom_smooth: Only one unique x value each group.Maybe you want aes(group = 1)?
geom_smooth: Only one unique x value each group.Maybe you want aes(group = 1)?
geom_smooth: Only one unique x value each group.Maybe you want aes(group = 1)?
geom_smooth: Only one unique x value each group.Maybe you want aes(group = 1)?
geom_smooth: Only one unique x value each group.Maybe you want aes(group = 1)?
geom_smooth: Only one unique x value each group.Maybe you want aes(group = 1)?
Finally do you think it would be possible to have a different colors for the different Subjects instead of one color per variable please?Can I add the regression line on every graphs?
Thank you for your help.

Note the warning Maybe you want aes(group = 1). All I've done is add group = 1 to aes for geom_smooth.
ggplot(data.2) +
geom_jitter(aes(value,Svolume, colour=variable),) +
geom_smooth(aes(value,Svolume, colour=variable, group = 1), method=lm, se=FALSE) +
facet_wrap(~variable, scales="free_x") +
labs(x = "Variables", y = "Svolumes")
Some unsolicited advice
You don't need to use
requireandlibrary, one or the other.You only need
aesonceYour example data didn't work - I had to fiddle with it to read it. See How to make a great R reproducible example? for advice.
Here's how I would write the ggplot code:
library(ggplot2)
require(reshape2)
data.2 = melt(data[3:9], id.vars='Svolume')
ggplot(data.2) +
aes(x = value, y = Svolume, colour = variable) +
geom_jitter() +
geom_smooth(method=lm, se=FALSE, aes(group = 1)) +
facet_wrap(~variable, scales="free_x") +
labs(x = "Variables", y = "Svolumes")
