[R] convering upper triangular matrix into vector

I have two symmetrical distance matrices and want to compute the correlation coefficient between them (after turning them into vectors).

Is there a way of selecting only the upper triangular part of each matrix, then convert this into a vector so I can compute the correlation?

Many Thanks
