Hello,
I am trying to figure out how to do a sum of items within a row. For
example, I have a data frame something like this:
A1 B1 ... A2 B2 ...
1 1 4 1 4
2 2 5 2 5
3 3 6 3 6
What I want, is for each row, to get A1 + A2, B1 + B2, etc. which would,
perhaps, give me a vector something like this c(2, 8, ... 4, 10 ... 6, 12).
Does anyone know of a simple way to do this?
Thanks a lot,
Q
