在R语言中如何将两张散点图画在一起？

Question

如题所述

Answer 1

例如vd2=c(-16.3,-12.2,-8.2,-3.9,0,5.9,9.7,13.2,18.1)
vd1=c(-16.6,-12.5,-8.8,-4.2,0,6,9.8,15,18.2)
y=c(-16,-12,-8,-4,0,4,8,12,16)
plot(y~vd1)
plot(y~vd2,col="red")
然后在require(ggplot2)
vd = rbind(data.frame(v=vd1, y=y, t=as.factor(1)), data.frame(v=vd2, y=y, t=as.factor(0)))
ggplot(vd, aes(x=v, y=y)) + geom_point(aes(color=t))
可能会下个程序包
