Hi all,
I want to combine two data sets (ZA and ZB to get ZAB).
The common variable between the two data sets is ID.
Data ZA
ID F M
1 0 0
2 0 0
3 1 2
4 1 0
5 3 2
6 5 4
Data ZB
ID v1 v2 v3
3 2.5 3.4 302
4 8.6 2.9 317
5 9.7 4.0 325
6 7.5 1.9 296
Output (ZAB)
ID F M v1 v2 v3
1 0 0 -9 -9 -9
2 0 0 -9 -9 -9
3 1 2 2.5 3.4 302
4 1 0 8.6 2.9 317
5 3 2 9.7 4.0 325
6 5 4 7.5 1.9 296
Any help is highly appreciated in advance,
Val
