Different y-axes

What's wrong?

I tried today's examples and just got only both labels printed one over
the other.

1. Brian Ripley
x <- 1:10
y <- rnorm(10)
z <- runif(10, 1000, 10000)
par(mar=c(5,4,4,4) + 0.1)  # Leave space for z axis
plot(x, y)
par(new=T)
plot(x, z, type="l", axes=F, bty="n", xlab="", ylab="")
axis(4, at=pretty(range(z)))
mtext(z, 4, 3)

2. Don MacQueen
x <- 1:5
y1 <- 1:5
y2 <- 25:21
plot(x,y1)
par(new=T)
plot(x,y2,yaxt='n',col='blue')
axis(4,y2)

You tell us: we don't know what you are seeing ....

mtext("z", 4, 3) was a copying error from me, but all the rest works.
That does plot the box, x axis and x label twice, which matters on some
devices, e.g. a plotter.

This is fine if you leave out the last line... Did that really come
from Brian?? mtext("z", 4, 3) might have been the intention.
you need at least ylab="" on the 2nd plot.

by now it works, thanks a lot!
true, but it was given as an example of "double" y-labels; maybe I just
misunderstood the intention.
