Dear List,
I have two data.frame of the following form:
A:
n V1 V2
1 12 0
2 10 8
3 3 8
4 8 4
6 7 3
7 12 0
8 1 0
9 18 0
10 1 0
13 2 0
B:
n V1 V2
1 0 2
2 0 3
3 1 9
4 12 8
5 2 9
6 2 9
8 2 0
10 4 1
11 7 1
12 0 1
Now I want to merge

Hi all,
the moment you hit the 'send' button you know the answer...
I approached a solution similar to this one given by Marc. But maybe
there is a better one? Even because this operation is done in a

Here's a solution that uses aggregate(), as suggested in the subject of this
thread.
m1 - cbind( n=c(1,2,3,4,6,7,8,9,10,13), v1=c(12,10,3,8,7,12,1,18,1,2),
v2=c(0,8,8,4,3,0,0,0,0,0) )
m2 - cbind( n=c(1,2,3,4,5,6,8,10,11,12), v1=c(0,0,1,12,2,2,2,4,7,0),
