_A_r_g_u_m_e_n_t_s:

  object: Object of class "biclustermd_sim"

similarity: A character vector indicating which similarity measure to
          plot. Can be any of '"Rand"', '"HA"', '"Jaccard"', or
          '"used"'. If '"used"', plot only the measure used as the
          stopping condition in the algorithm). By default ('NULL') all
          three are plotted. When plotted, the used measure will have
          an asterisk.

   facet: If 'TRUE' (default), each similarity measure will be in its
          own plot. if 'FALSE', all three similarity measures for rows
          and columns are given in one plot.

    ncol: If faceting, the number of columns to arrange the plots in.
