Actually, to correct my initial post, I'd be interested in *combinations* not *permutations*. So to restate and revise: ID time 5m_block 1 8:00 1 2 8:02 1 3 8:02 1 4 8:04 1 5 8:06 2 6 8:07 2 7 8:09 2 For 5 minute time blocks, I'd want to output a dataset that looks like this: Dyad 12 13 14 23 24 34 56 57 67 For 5m bands, I'd want: Dyad 12 13 14 23 24 25 34 35 45 46 56 57 67 On Thu, Dec 19, 2013 at 2:29 PM, Douglas Levy <douglas_levy@post.harvard.edu> wrote: > Hi All, > I'm trying to create a dataset of all paired permutations of subject > IDs within time blocks or alternatively time bands.
