[R] display of ECDF

[Bogdan Tanasa]

Dear all,

please could you advise me on the following : I would like to display a few
CDF data (the R code is below), by using a set of numerical BREAKS on a X
axis to be shown at EQUAL DISTANCE from each other (although numerically,
the BREAKS are on log10 axis and do not reflecting an equal distance):

df <- data.frame(
  x = c(rnorm(100, 0, 3), rnorm(100, 0, 10)),
  g = gl(2, 100)
)

breaks=c(0.001, 0.01, 0.1, 1, 5, 10, 20, 30, 100)

ggplot(df, aes(x, colour = g)) + stat_ecdf()  +
scale_x_log10(breaks=breaks),

how shall I do it ? thanks a lot !
