Hola!
I think this have been asked (and answered) many times, so you
could have tried to search the archives!
But, a simple example:
> x <- 1:10
> y1 <- 1:10
> y2<- rev(seq(1,1000, length=10))
> y2
[1] 1000 889 778 667 556 445 334 223 112 1
> plot(x,y1,ann=FALSE)
> axis(2, at=c(2,4,6,8), labels=as.character(c(2,4,6,8)))
# this gives a mark at 10 also! a bug?
> points(x,y2/100,col="red")
> axis(4, at=c(2,4,6,8), labels=as.character(c(200, 400, 600, 800)))
