I'm not sure I completely understand your question, but I think the solution
to your problem is the reshape function in the reshape package. Here is a
silly example of how it would work:
> V<-matrix(rbinom(15,4,.5),nrow=3)
> X<-data.frame(A=c("A","B","C"),V=V)
> X
A V.1 V.2 V.3 V.4 V.5
1 A 1 2 3 3 3
2 B 4 3 0 2 2
3 C 2 3 2 1 2
> reshape(X,direction="long",varying=c("V.1","V.2","V.3","V.4","V.5"))
A time V id
1.1 A 1 1 1
2.1 B 1 4 2
3.1 C 1 2 3
1.2 A 2 2 1
2.2 B 2 3 2
3.2 C 2 3 3
1.3 A 3 3 1
2.3 B 3 0 2
3.3 C 3 2 3
1.4 A 4 3 1
2.4 B 4 2 2
3.4 C 4 1 3
1.5 A 5 3 1
2.5 B 5 2 2
3.5 C 5 2 3
Your two columns of interest are A and V. The time column lets you know
from which column the V came.
