Subject: little manipulation on data frame
Dear all,
I have data like 3 coulmns and many rows. Each entry
is less than 10.
Example
x y z
1 5 3 2
2 3 7 8
3 8 9 5
4 5 4 6
--------------------------
---------------------------
I have to sum entries of each coulmn (seperately) till
it be 10. This i have to start for each row. And I
want to assign no. of rows needed including that row
too(it to be 10 or 10+, the moment it exceeds 10, i
need to stop and count the no. of rows)in additional
coulmns say N1 (corresponding to coulmn x), N2 (y) and
N3 (z).
I want my new table like
x y z N1 N2 N3
1 5 3 2 3 2 2
2 3 7 8 2 2 2
3 8 9 5 2 2 2
4 5 4 6 depends upon next row
If anybody knows it, please help me.
Thanking you.
Best regards,
N. Dey.
