Hi,thanks a lot for the answer. I think that my problem is before packages. I
have a large amount of different datasets and I had a random look on their
histograms. I know that some of them look like the combination I have explained
(exponential+pareto, exponential+gamma) but I am not sure still.I wanted to
know if there is a "preliminary" approach where a fitting algorithms tries some
of the suggested combinations and give me hints where to focus my future
research.I will have a look on the package you suggested.
RegardsAlex

Have you considered "distr" and related packages?
If this does not solve your problem, have you considered
searching with "findFn" in the "sos" package? If that still does not
produce sufficient enlightenment, please try this list again with
"commented, minimal, self-contained, reproducible code" describing what
you want in a bit more detail (as indicated at the end of emails on this
list).
