A convenient function to turn a matrix into a vector of non-redundant components. If the matrix is non-symmetric, returns a vector containing all entries of the matrix. If the matrix is symmetric, only returns the upper triangle and optionally the diagonal.
vectorizeMatrix(M, diag = FALSE)the matrix or data frame to be vectorized.
logical: should the diagonal be included in the output?
A vector containing the non-redundant entries of the input matrix.
