The cdf of the Gumbel distribution is exp(-exp(-x)), not the density.
The easiest way to plot the density is probably to download package evd
and use
library(evd)
plot(dgumbel, -2, 5)

Hi R lovers!
Are there any means to define and plot a function given the equation that
specifies the function?
For example I'd like to plot and work with the Gumbel Distribution density
defined by
Lambda(x)=exp(-exp(-x))
My question may appear very simple but I haven't got an idea yet about how
to do that. I could plot something with x a vector/set of value but I don't
know how to proceed with x belonging to a continuous interval
Thanks for any help.
