Hi,
Here is an example of the question I posted yesterday. Suppose there are 10 data sets, each contains 100 values. In data set #3, #5, #9, there are different subgroups. Is there a way to identify these kind of data set? data=matrix(runif(1000), 10, 100);data[3,61:90]=runif(30)+1; data[5,1:40]=runif(40)+3; data[5,81:100]=runif(20)+5; data[9,1:20]=runif(20)+2; data[9,31:60]=runif(30)+4; data[9,71:90]=runif(20)+6; Many thanks! /Mike On Fri, May 16, 2008 at 4:52 PM, mike Ad. wrote: > Dear group, > > I have hundreds > of independent data sets, each data sets contains >100 values.
