Hello,
Can you specify what you mean by deleting exactly?
Do you want to have zero in the diagonal or do you want to extract the
non-diagonal part?
Besides your matrix is not a square matrix. Do you really want to
extract the non-diagonal part of a non square mat

May be something like this ?

matrix(as.numeric(aa)[!as.numeric(aa) %in% diag(aa)],2,3)
[,1] [,2] [,3]
[1,]24
Jeremie's suggestion of course will fail if some of the off-diagonal
elements are the same as those on the diagonals.
The request doesn't make a lot of sense to me, but if "m" is the matrix,
m[row(z) != col(z)]
reliably extracts the vector of non-diagonal entries, which can then be
dimensioned
