Don't know if I understand your last comment but I surely don't think
that the Weibull and Gumbel distributions are the same. See their
density function on e.g. Wikipedia.
Then *why* did you answer Ms. Botto's question about the Gumbel
distribution with a pointer to the help on the *Weibull* distribution? I
was very puzzled by this and thought that I must be
missing/misunderstanding something.
cheers,

Thankyou very much Frede. It wasn't any home I am just trying to put my grip on
distribution. Believe it or not, I came to know for the first time that weibull
and gumbel distributions are same. :(

Is this a home work problem?
See
Weibull package:stats R Documentation
The Weibull Distribution
Description:
Density, distribution function, quantile function and random
generation for the Weibull distribution with parameters 'shape'
and 'scale'.
Usage:
dweibull(x, shape, scale = 1, log = FALSE)
pweibull(q, shape, scale = 1, lower.tail = TRUE, log.p = FALSE)
qweibull(p, shape, scale = 1, lower.tail = TRUE, log.p = FALSE)
rweibull(n, shape, scale = 1)

Subject: [R] gumbel distribution
Dear useRs,
I need some examples of gumbel probability plots in R. i'll be extremely
grateful if you could share the codes of a working example.
