Well, I don't think that is what Shane wants either but my suggestion is
clearly wrong. I was reading the question as a dual axis not just a
suplimentary , equivalent value axis. DUH.
What I think he wants is what IIRC Petr orginally suggested which is this..
Create the data to be graphed
x<-1:5
y1<-x
y2<-x^2
# Set the par values
# op <- par(las=1,xaxs="r",mai=c(1,1,1,1))
# Draw the plot
plot(x,y1,xlim=c(0,5),ylim=c(0,5), ylab="y1", las = 1)
title(main="Equvalent Axes in R")
axis(3, labels = c("10", "100", "1,000", "10,000", "100,000"), at=1:5)
text(12, 50, "y2", srt = 270, xpd = TRUE)
par(op) # reset par
