[R] Is there any method to identify the distribution of a given dataset?

[Bert Gunter]

Below. Brief summary is: You **need** to consult a statistician. You know
far too little statistics to do statistical analysis on your own.

It's important to identify the distribution of a dataset before do analysis
and inference.

-- Not necessarily. Indeed, often not.

 Is there any method to identify the distribution of a given
dataset?
 -- Yes. It's discrete. The question you mean to ask is : How do I choose a
suitable model for my data?

 For example, I want to identify a dataset belong to normal of
poisson distribution, how can I do that?

-- Whew! That you even ask this question is why you need to work with
someone who knows more about statistics. No insult intended. It's kind of
like me asking a biologist what's the difference between a mitochondrion and
a nucleus. If I know so little about cell biology that I must ask, I
probably need to work with someone more knowledgeable.
