I know this is likely very simple. I want to change a matrix that was given to me not sorted by timestamp to sorted by timestamp. It was sorted by CRAH_Name. There are 264k records initially. The CRAH names start at 11 and go to 98 but there are a number of missing values (CRAH_Name), total approx. 50. A small example of the given matrix Time_Stamp Power CRAH_Name 4/16/2012 00:00 3.4862 11
