[R] Re : Custom axis

[joris.dewolf at cropdesign.com]

What about the other way round?

x <- 1:10
y <- rnorm(10,10,1)
x2 <- 3*x + 2
plot(y ~ x2, xaxt = "n")
axis(side=1,at = x2, labels = x)

Maybe I do not explain well what I would like to do. I do not want to
change the labels of the axis, but the scale. What I want is a general
procedure for changing the scale. Its like using a logarithmic scale on a
plot. Labels are the same, but the increases of x along the x-axis are
defined by a known monotone and continuous function.

Dear R users,

I would like to draw a plot with a custom scale for the axis. More
precisely, instead of plotting  y on x, I want to plot y on a monotone
function of x (for instance a*x+b). Which command and/or package should I
use in order to get this result?

Thanks

Florent Bresson
