如何在同一图中绘制两条累积分布曲线作为线型 [英] How can I plot two cumulative distributions curve as line type in same plot

问题描述

我想在经验累积分布曲线上绘制威布尔分布的累积分布曲线.

I want to plot cumulative distributions curve for Weibull distribution over empirical cumulative distribution curve.

我已经尝试过几次了，但是并没有达到我想要的方式.这是命令:

I have tried with this several times but it does not serve the way I want. Here is the command:

x<-(SIZEDIST$AVG.µm.)
x
plot(x,pweibull(x,shape=1.120662,scale=18.496778),type="l",col=4)
plot(ecdf(x),add=TRUE)

推荐答案

使用lines代替plot

plot(x,pweibull(x,shape=1.120662,scale=18.496778),type="l",col=4)
lines(ecdf(x),col='red')
