Off topic:even display of unevenly spaced numbers on x/y coordinates

Question

[Bogdan]

Dear all,

please would you advise on how I could make an even display of unevenly spaced number on a graph in R. For example, considering the code below :

BREAKS = c(0, 0.1, 1, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500)

a <- seq(0,100,0.1)
b <- seq(0,1000,0.1)

plot(ecdf(a), col="red", xlim=c(0,100), main=NA, breaks=BREAKS)
plot(ecdf(b), col="green", xlim=c(0,100), add=T, breaks=BREAKS)

I would like to show on X axis (0, 0.1, 1 and 10) spaced in an equal/even manner.

thanks !
