在r中的ggplot的绘图区域内添加表格 [英] Adding table within the plotting region of a ggplot in r
本文介绍了在r中的ggplot的绘图区域内添加表格的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想在ggplot中添加一个突出显示网站的坐标表。 使用以前的 question 作为示例数据:
set.seed(1)
mydata< - data.frame(a = 1:50,b = rnorm(50))
ggplot(mydata,aes(x = a, y = b))+
geom_point(color =blue)+
geom_point(data = mydata [10:13,],aes(x = a,y = b),color =red ,size = 5)
我想将下表添加到图的右下角绘图区域。任何建议?
$ p $ 表<-cbind(sites = c(site 1,site 2,site 3 ,site 4),mydata [10:13,])
表
网站ab
网站1 10 -0.3053884
网站2 11 1.5117812
site 3 12 0.3898432
site 4 13 -0.6212406
解决方案
您可以使用 ggplot2
的 annotation_custom
与 tableGrob
来自 gridExtra
包。
library(ggplot2)
pre>
library(gridExtra)
set.seed(1)
mydata< - data.frame(a = 1:50,b = rnorm(50))
mytable< - cbind (sites = c(site 1,site 2,site 3,site 4),mydata [10:13,])
k < - ggplot(mydata,aes(x = a ,y = b))+
geom_point(color =blue)+
geom_point(data = mydata [10:13,],aes(x = a,y = b)红色,size = 5)+
annotation_custom(tableGrob(mytable),xmin = 35,xmax = 50,ymin = -2.5,ymax = -1)
I would like to add a table of the coordinates of highlighted site in a ggplot.
Using a previous question as example data:
set.seed(1) mydata <- data.frame(a=1:50, b=rnorm(50)) ggplot(mydata,aes(x=a,y=b)) + geom_point(colour="blue") + geom_point(data=mydata[10:13, ], aes(x=a, y=b), colour="red", size=5)
I would like to add the following table to the lower right-hand corner of the plot within the plotting region. Any advice?
table<-cbind(sites=c("site 1","site 2","site 3","site 4"),mydata[10:13,]) table sites a b site 1 10 -0.3053884 site 2 11 1.5117812 site 3 12 0.3898432 site 4 13 -0.6212406
解决方案You can use
ggplot2
'sannotation_custom
with atableGrob
from thegridExtra
package.library(ggplot2) library(gridExtra) set.seed(1) mydata <- data.frame(a=1:50, b=rnorm(50)) mytable <- cbind(sites=c("site 1","site 2","site 3","site 4"),mydata[10:13,]) k <- ggplot(mydata,aes(x=a,y=b)) + geom_point(colour="blue") + geom_point(data=mydata[10:13, ], aes(x=a, y=b), colour="red", size=5) + annotation_custom(tableGrob(mytable), xmin=35, xmax=50, ymin=-2.5, ymax=-1)
