[英]Error when making a boxplot with ggplot2
I'm newbie at using ggplot2 with R. When I run this script 我是ggplot2与R的新手。运行此脚本时
var<-schz.[1,]
values<-schz.[,-1]
ggplot(data=schz., aes(var, values)) + geom_boxplot()
I obtained this error message: 我收到此错误消息:
Don't know how to automatically pick scale for object of type data.frame.
不知道如何为data.frame类型的对象自动选择比例。 Defaulting to continuous.
默认为连续。 Error: Aesthetics must be either length 1 or the same as the data (80): x, y
错误:美学的长度必须为1或与数据(80)相同:x,y
The dataset is the following: [ https://drive.google.com/file/d/0B7tO-O0lx79FZERvcHJUSmxNSTQ/view?usp=sharing] 数据集如下:[ https://drive.google.com/file/d/0B7tO-O0lx79FZERvcHJUSmxNSTQ/view?usp=sharing]
Someone can tell me what's wrong? 有人可以告诉我怎么了? I understand it's something with the definition of x and y in the ggplot2 function, but I can't fix it!
我了解这与ggplot2函数中x和y的定义有关,但我无法解决!
You need to reshape your data into long format instead of wide. 您需要将数据重整为长格式而不是宽格式。 I use the melt function from the reshape2 package, but you can also use gather from the tidyr package.
我使用reshape2包中的melt函数,但是您也可以使用tidyr包中的collect。
Try: 尝试:
library(reshape2)
ggplot(data=melt(schz.), aes(variable, value)) + geom_boxplot()
