Great. Your suggestion is most welcome, everything is clear now.
Thank you for your time, Duncan!

Update:
I had tried, immediately after launching the console:

which did not seem to affect .Random.seed. But now I try:

which seems to force .Random.seed to regenerate from current time.
Can I feel confident to have solved the problem?
Thanks!
Hello,
I have tried a few searches without luck before posting, since this one
seems a pretty basic question.
I am using R 2.7.0 on WinXP, as I have long started using this version for
my thesis work and am reluctant to update fearing consistency/backward
compatibility issues could happen.

you could get a cleaner solution using ?cut to split your data

Thank you very much for your help.

Using R 2.7.0 under WinXP.
I need to write a function that takes a non-negative vector and returns the
parallell maximum between a percentage of this argument and a fixed value.
Both the percentages and the fixed values depend on which interval x falls
in. Intervals are as follows:

d back to Ben yesterday and the post was not accepted yet, so it
probably does not show in the thread, but there I stated I was going to use
a beta distribution, so my problem is solved by now. If you want, we may
continue this conversation privately.
Many thanks.

I am trying to model damage from fire losses (given that the loss occurred).
Since I have the individual insured amounts, rather than sampling dollar
damage from a continuous distribution ranging from 0 to infinity, I want to
sample from a percent damage distrib
Dear useRs,
Is there a way one can add x-axis values to a histogram? Example:
z = rgamma(n=1000, shape = 8, scale = 1000)
hist(z, breaks = 30)
Currently I see 4 x-axis values: 5000, 1, 15000, 2. Can I add more
values or modify the ones currently showing? I tried ?hist, yet couldn't
work

Maybe a little little late, but if by chance you happened to create the
English version of the document, I would also be interested in reading it.
Thank you

I've been reading your suggestions and I'd like to share my thoghts, which
