[R] To represent on the same plot the relation (y1, x) and (y2, x)
Hi,
May be this helps:
?x<- 1:10
?set.seed(28)
?y1<- rnorm(10)
set.seed(485)
?y2<- rnorm(10)
?plot(x,y1,col="red",type="b",ylab="y1:y2")
lines(y2,col="blue",type="b")
legend("topleft", legend = c("y1",
"y2"),text.col=c("red","blue"))
#or
library(ggplot2)
dat1<- data.frame(x,y1,y2)
ggplot(dat1,aes(x))+geom_line(aes(y=y1,colour="y1"))+
? geom_line(aes(y=y2,colour="y2")) +ylab("y1:y2")
A.K.

Hello,
I have 3 vectors x, y1 and y2
I would like to represent on the same plot the two graph (y1, x) and
(y2, x).
Is it possible with ggplot ? other package ?
Thanks for your help
