Dear group,

I have hundreds
of independent data sets, each data sets contains >100 values. In some data sets, all the values can be classified into several groups with clear difference between groups; while in some other data sets, all the values are randomly distributed. I would like to find a statistics method to automatically pick out the data sets which have group pattern, or specifically found data sets have certain number of groups, e.g. 2, 3, 4.

Are there
any functions or packages that could solve this issue, or any other suggestions?  Many Thanks!
