Hi, I have a data set in long form and i want to convert it to wide. I have tried the 'reshape' command (using various combinations of variables) but it won't work. The problem is, there aren't any unique j values for the i's. The variables I want to be sorted on are the id, collect_date and order_type. The for it to read across for drug_code and drug_result (They are all string variables). Below as an example of how my data is set up. Id collect_date order_type drug_code drug_result 34 03aug2010 CFS Amp SS 34 03aug2010 CFS Oxy 0.1-SS 34 10aug2010 CFS Methc R 57 05mar2008 Urine Amox R 57 05mar2008 Urine Amik 0.001-SS-HIDE 87 07sep2009 Blood Oxy HIDE 62 12oct2007 Urine Vanc 0.063-SS 62 12oct2007 Urine Methc 0.063-SS 62 12oct2007 Urine Vanc R-HIDE 62 12oct2007 Blood Amp SS Any suggestions?
