R中同一图上的频率和累积频率曲线 [英] Frequency and cumulative frequency curve on the same graph in R
本文介绍了R中同一图上的频率和累积频率曲线的处理方法,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
您可以使用这些数据。
< (c(10,15,20,25,30,35,40,45,50)),频率= c(0,1,5,10,20,10 ,6,3,0)),.Names = c(speed,frequency),row.names = c(NA,-9L),class =data.frame)
$mydata< -structure(list(speed = c(10,15,20,25,30,35,40,45,50),频率= c(0,1,5,10,20,10,6,3,0)),NAME = c( 速度,频率),row.names = c(NA,-9L),class =data.frame)
library(ggplot2)
qplot(data = mydata,
x = speed,
y = frequency,
geom = c(point,line))+
geom_line(aes(y = cumsum(frequency)))
或
频率栏
mydata $ sum.freq< -wit h(mydata,cumsum(频率))
library(reshape)
qplot(data = melt(mydata,id.vars =speed),
x = speed,
y = value,
geom = c(point,line),facets = variable〜。)
Is there a way (in R with ggplot or otherwise) to draw frequency and cumulative frequency curves in a single column (two rows) i.e. one top of the other such that a given quartile can be shown on both the curves using straight lines? I hope I am clear on this..
You may use this data..
mydata<-structure(list(speed = c(10, 15, 20, 25, 30, 35, 40, 45, 50),frequency = c(0, 1, 5, 10, 20, 10, 6, 3, 0)), .Names = c("speed","frequency"), row.names = c(NA, -9L), class = "data.frame")
解决方案mydata<-structure(list(speed = c(10, 15, 20, 25, 30, 35, 40, 45, 50),frequency = c(0, 1, 5, 10, 20, 10, 6, 3, 0)), .Names = c("speed","frequency"), row.names = c(NA, -9L), class = "data.frame") library(ggplot2) qplot(data=mydata, x=speed, y=frequency, geom=c("point", "line"))+ geom_line(aes(y=cumsum(frequency)))
or
Add a cumulative frequency column
mydata$sum.freq<-with(mydata, cumsum(frequency)) library(reshape) qplot(data=melt(mydata, id.vars="speed"), x=speed, y=value, geom=c("point", "line"), facets=variable~.)
