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

[GreenBrower]

Thanks for everybody, I feel shame after I posting the above message because
I found there is a tutorial "Fitting Distributions with R" on
http://cran.ii.uib.no/ It's seems not everybody check the dataset's
distribution.
