Bon jour, I am not clear exactly what you are looking for. When I first read the email I though you wanted to know if something in vector 2 was in vector 1 but after rereading it I am not sure.
If I was correct the first time I think something like vector2 %in% vector1 will do it. If I am wrong, and I think I am, would you explain the problem a bit more, perhaps with some small data vectors?
