All, I have data that looks like below. For each id there may be more than one value per day. I want to select a random value for that day for that id. The end result would hopefully be a matrix with the id as rows, date as columns and populated by the random hab value. Thanks to someone on here (Jim) I know how to do the matrix, but now realize I need to randomly select some of my values. All help is appreciated. jm id, date, loctype, habtype 50022 1/25/2006 0 6 50022 1/31/2006 0 6 50022 2/8/2006 0 6 50022 2/13/2006 0 6 50022 2/15/2006 0 6 50022 2/24/2006 0 6 50022 3/2/2006 0 6 50022 3/9/2006 0 6 50022 3/16/2006 0 6 50022 3/24/2006 0 6 50022 4/9/2006 0 3 50022 4/18/2006 0 6 50022 4/27/2006 0 3 50022 5/23/2006 1 3 50022 5/23/2006 1 6 50022 5/24/2006 1 3 50022 5/24/2006 1 3 50022 5/24/2006 1 3 50022 5/24/2006 1 3 50022 5/25/2006 1 3 50022 5/25/2006 1 3 50022 5/25/2006 1 3 50022 5/26/2006 1 5 50022 5/26/2006 1 3 50022 5/27/2006 1 5 50022 5/27/2006 1 3 50022 5/28/2006 1 3 50022 5/29/2006 1 3 50022 5/30/2006 1 5 50022 5/30/2006 1 3 50022 5/31/2006 1 3 50022 5/31/2006 1 3 50022 6/1/2006 1 3 50022 6/2/2006 1 3 50022 6/3/2006 1 3 50022 6/4/2006 1 3 50022 6/5/2006 1 3 50022 6/6/2006 1 5 50022 6/6/2006 1 5 50022 6/6/2006 1 5 50022 6/6/2006 1 3 50022 6/6/2006 1 3 50022 6/7/2006 1 5 50022 6/7/2006 1 3 50022 6/7/2006 1 3 50022 6/7/2006 1 3 50022 6/7/2006 1 3 50022 6/8/2006 1 3 50022 6/8/2006 1 3 50022 6/8/2006 1 3 50022 6/9/2006 1 5 50022 6/10/2006 1 3 50022 6/11/2006 1 5
