[R] Method for checking automatically which distribtions fits a data

[Stephen Tucker]

I don't know that there is a single function, but you can perhaps apply a sequence of available functions - 

For instance, you can use fitdistr() in library(MASS) to estimate optimal parameters for a candidate set of distributions; then look at each fit and also compare the deviance among the fits (possibly penalizing distributions which require more parameters - for instance, using the Akaike Information Criterion(?)).

Subject: [R] Method for checking automatically which distribtions fits a data

Hi,

Suppose I have a vector of data.
Is there a method in R to help us automatically
suggest which distributions fits to that data
(e.g. normal, gamma, multinomial etc) ?
