This is what you are trying to get at I think:

dev.off()   ## start with a new graphics device
# X11() or postscript()
#par(mar = c(3,3,1,3), oma = c(0,0,0,0), mgp = c(2, 1, 0), bg = "white")
par(mar = rep(5,4))
plot(x<-rnorm(100),y<-rnorm(100), ylab = "This is y", xlab = "This is x")
z<-rnorm(100)*250
par(new=T)   ## Tell R not to reinitialize graphic device
             ## for subsequent plots
plot(x,z,col='blue',axes=F, xlab="", ylab="")
axis(side=4,col.axis='blue', labels = T)
mtext("This is z", 4, 2, col = "blue")
par(new=F)
