1 2	calculate_document_pair_distances(document_term_matrix, document_indicies, distance_method = "cosine")

`document_term_matrix`	A sparse matrix object of class "simple_triplet_matrix", or a dense matrix object, with documents as rows and vocabulary entries as columns.
`document_indicies`	A numeric vector of length two (document_a_row_index, document_b_row_index), or a list object with each entry containing a vector of length two as described above.
`distance_method`	Can be one of "cosine" or "euclidean". Defaults to "cosine".
