Re: [R] Adding Legend about two quantile lines at ggplot

Hi: scale_manual() is a little tricky when you build the legend from within the plot. I used shorter labels than you, but this worked for me: ggplot(mydata, aes(y=score2, x=score1)) + geom_point() + stat_quantile(quantiles=c(0.50), aes(colour='red'), size = 1) + stat_quantile(quantiles=c(0

[R] Adding Legend about two quantile lines at ggplot

Hi, all. I'd like to add legend on my graph but I can't. My code is follows. library(ggplot2) score1<-rnorm(100,0,5) score2<-rnorm(400,10,15) mydata<-data.frame(score1,score2) ggplot(mydata,aes(y=score2,x=score1))+geom_point()+stat_quantile(quantiles=c(0.50),col="red")+stat_quantile(quantiles=c(0
