I have a question on RowSums.
Lets say i have a timeSeries table
A B C
1/1/90 NA 1 1
1/2/90 NA 1 1
1/3/90 NA 1 1
1/4/90 NA 1 1
1/5/90 1 1 1
1/6/90 1 1 1
if i use RowSums, i will get
1/5/90 3
1/6/90 3
but i want
1/1/90 2
1/2/90 2
1/3/90 2
1/4/90 2
1/5/90 3
1/6/90 3
I cant figure out a way without doing loop.
Thanks
Cameron
