Hi All, I have a data set with 11000 rows & 19 columns. I have 2 columns on which I need to summarize the data:- Date & Weight. Snapshot is : Date 13/03/2015 31/03/2015 15/03/2015 17/03/2015 17/03/2015 11/3/2015 11/3/2015 19/03/2015
CHG_WT 0 0 0 770 3,730 70 10 500 Now I need to summarize this data based on Day wise trend of weight however I have tried bifurcating and truncating the date and saw multiple options over the web - zoo package, iso week etc but I am not sure on how to reach to this analysis. If you experts can please suggest how to achieve the requirement.
