[R] A "matching problem"

Dear all, I was encountering with a typical Matching problem and was 
wondering whether R can help me to solve it directly.

Let say, I have 2 vectors of equal length:
vector1 <- LETTERS[1:6]
vector2 <- letters[1:6]

Now I need to match these 2 vectors with all possible ways like:

(A,B,C,D,E) & (a,b,c,d,e) is 1 match. Another match can be (A,B,C,D,E) & 
(b,a,c,d,e), however there cant be any duplication.

Is there any direct way to doing that in R?

Thanks and regards,
