Description Usage Arguments Value Author(s)

This function takes a sits tibble and returns a matrix representation of a similarity graph where only the most similar samples are connected.

1	.al_s2_bild_closest_vertex_graph(samples_tb, sim_method, closest_n)

`samples_tb`	A sits tibble with both labelled and unlabelled samples (i.e. NA).
`sim_method`	A character. A method for computing the similarity among samples. See proxy::simil for details.
`closest_n`	An integer. The number of most similar samples to link in the graph.

           A lower triangular matrix. The matrix's upper
                   triangular part along its principal diagonal are set
                   to NA. The rows in the matrix's lower triangular part
                   are non-NA for the closest_n elements.
