ggplot:为每个连续的x组排列多个y变量的箱形图 [英] ggplot: arranging boxplots of multiple y-variables for each group of a continuous x
问题描述
我想为连续x变量的组创建多个变量的箱型图。这些箱子图应该排列在一起,用于每组x.
数据如下所示:
$
require(ggplot2)
require(plyr)
library(reshape2)
x< (100)
y.1 - rnorm(100)
y.2 - rnorm(100)
y.3 - rorm(100)$ b $ (x,y.1,y.2,y.3,y.4))b_4 < - rnorm(100)
df < - as.data.frame(cbind
然后我融化了
dfmelt < - melt(df,measure.vars = 2:5)
此解决方案中显示的facet_wrap(
这显示了每个旁边的y变量
ggplot(dfmelt)+
geom_boxplot(aes(x = x,y = value,fill = variable))+
facet_grid(〜变量)
现在我想为x的每个bin生成一个这样的图。
什么需要改变或添加?
不完全确定你在找什么。这是关闭吗?
library(ggplot2)
library(plyr)
ggplot(dfmelt,aes(x = factor(round_any (x,0.5)),y = value,fill = variable))+
geom_boxplot()+
facet_grid(。〜variable)+
labs(x =X(binned) )+
theme(axis.text.x = element_text(angle = -90,vjust = 0.4,hjust = 1))
编辑(回复OP的评论)
您可以将Y的每个相邻放入每个垃圾箱通过取出 facet_grid(...)
调用,但我不推荐它。
ggplot(dfmelt,aes(x = factor(round_any(x,0.5)),y = value,fill = variable))+
<
geom_boxplot()+
labs( x =X(binned))+
theme(axis.text.x = element_text(angle = -90,vjust = 0.4,hjust = 1))
$ b $ p $ < b
如果你必须这样做t他的方式,使用方面仍然更清楚:
dfmelt $ bin < - factor(round_any(dfmelt $ x,0.5))
ggplot(dfmelt,aes(x = bin,y = value,fill = variable))+
geom_boxplot()+
facet_grid(。〜bin,scales =free)+
labs(x =X(binned))+
theme(axis.text.x = element_blank())
请注意,在
dfmelt
中添加了bin
列。这是因为在facet_grid(...)
公式中使用因子(round_any(x,0.5))
doesn' t工作。I would like to create boxplots of multiple variables for groups of a continuous x-variable. The boxplots should be arranged next to each other for each group of x.
The data looks like this:
require (ggplot2) require (plyr) library(reshape2) set.seed(1234) x <- rnorm(100) y.1 <- rnorm(100) y.2 <- rnorm(100) y.3 <- rnorm(100) y.4 <- rnorm(100) df <- as.data.frame(cbind(x,y.1,y.2,y.3,y.4))
which I then melted
dfmelt <- melt(df, measure.vars=2:5)
The facet_wrap as shown in this solution ( Multiple plots by factor in ggplot (facets)) gives me out each variable in an individual plot, but I would like to have the boxplots of each variable next to each other for each bin of x in one diagram.
ggplot(dfmelt, aes(value, x, group = round_any(x, 0.5), fill=variable))+ geom_boxplot() + geom_jitter() + facet_wrap(~variable)
This shows the y-variables next to each other but does not bin x.
ggplot(dfmelt) + geom_boxplot(aes(x=x,y=value,fill=variable))+ facet_grid(~variable)
Now I would like to produce such a plot for each bin of x.
What has to be changed or added?
解决方案Not exactly sure what you're looking for. Is this close?
library(ggplot2) library(plyr) ggplot(dfmelt, aes(x=factor(round_any(x,0.5)), y=value,fill=variable))+ geom_boxplot()+ facet_grid(.~variable)+ labs(x="X (binned)")+ theme(axis.text.x=element_text(angle=-90, vjust=0.4,hjust=1))
EDIT (response to OP's comment)
You can put the Y's next to each other in each bin by just taking out the
facet_grid(...)
call, but I don't recommend it.ggplot(dfmelt, aes(x=factor(round_any(x,0.5)), y=value, fill=variable))+ geom_boxplot()+ labs(x="X (binned)")+ theme(axis.text.x=element_text(angle=-90, vjust=0.4,hjust=1))
If you have to do it this way, it's still clearer using facets:
dfmelt$bin <- factor(round_any(dfmelt$x,0.5)) ggplot(dfmelt, aes(x=bin, y=value, fill=variable))+ geom_boxplot()+ facet_grid(.~bin, scales="free")+ labs(x="X (binned)")+ theme(axis.text.x=element_blank())
Note the addition of a
bin
column todfmelt
. This is because usingfactor(round_any(x,0.5))
in thefacet_grid(...)
formula doesn't work.这篇关于ggplot:为每个连续的x组排列多个y变量的箱形图的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
