R: How to get something like adjacency matrix, but on the intersection
value of third column?

I have data frame like this:
V1 V2 LABEL
1 83965 891552 A
2 88599 891552 B
3 42966 891552 C
4 83965 891553 D
5 88599 891553 D
6 42966 891553 B
How can I convert it to something like adjacency matrix, but on the
intersection of colum-row i would like to have, the third colum value,
like that:
891552 891553
42966 C B
83965 A D
88599 B D
