Hi Jim,
I did not try merge because I thought it only adds variables instead of
cases. Below is what I am trying to do. When I joined data1 and data2, I
was was expecting three variables: r1, r2 and r3 with r2 and r3 presenting
missing values where they did not exist in the first place. V
> r1<-c(1,1,2,3)
> r2<-c(2,1,2,2)
> r3<-c(2,1,4,1)
> data1<-cbind(r1,r2)
> data2<-cbind(r1,r3)
> data1
r1 r2
[1,] 1 2
[2,] 1 1
[3,] 2 2
[4,] 3 2
> data2
r1 r3
[1,] 1 2
[2,] 1 1
[3,] 2 4
[4,] 3 1
> data<-rbind(data1, data2)
> data
r1 r2
[1,] 1 2
[2,] 1 1
[3,] 2 2
[4,] 3 2
[5,] 1 2
[6,] 1 1
[7,] 2 4
[8,] 3 1
> data3<-cbind(r2, r1)
> data_test<-rbind(data1, data3)
> data1
r1 r2
[1,] 1 2
[2,] 1 1
[3,] 2 2
[4,] 3 2
> data3
r2 r1
[1,] 2 1
[2,] 1 1
[3,] 2 2
[4,] 2 3
> data_test
r1 r2
[1,] 1 2
[2,] 1 1
[3,] 2 2
[4,] 3 2
[5,] 2 1
[6,] 1 1
[7,] 2 2
[8,] 2 3
