I have a dataset like

Trial     treat1   treat2

123       23.2      34.2

234       78          87

 

Now i want a last column naming all with sum of the rows

Trial     treat1   treat2

123       23.2      34.2

234       78          87

'all' as trial,
sum(treat1) as treat1,

I am always very leery of any inserted summary rows inside a data set. What happens if you run the same summary program later on the same data? Or you run a report procedure like Proc Report that generates summary totals. You have now included the summary into a new summary.

 

At a very minimum I would add an indicator variable to show that the row is indeed some sort of summary and the other rows aren't with appropriate label for the indicator.
