Hi Arnaud,
No problem.
Try,
x<- 1:10
set.seed(28)
y1<- rnorm(10)
set.seed(485)
y2<- rnorm(10,25)
library(plotrix)
twoord.plot(x,y1,y2,lylim=c(-2,2),rylim=c(20,30),ylab="y1",rylab="y2",lcol=2,rcol=4,main="y1,
y2 vs. x")
A.K.

Thank you Arun
But have you a solution if y1 and y2 have not the same unit (ex : the
unit of y1 is meter and the unit of y2 is Kg) and if I want the axe of
y1 at the left of the plot and the axe of y2 at the rigth of the plot....
