_D_e_s_c_r_i_p_t_i_o_n:

     Computes either the Wilcoxon Rank Sum or Signed Rank Statistics
     for all rows of a matrix simultaneously.

_U_s_a_g_e:

       rowWilcoxon(X, cl, rand = NA)

_A_r_g_u_m_e_n_t_s:

       X: a matrix in which each row corresponds to a variable, and
          each column to an observation/sample.

      cl: a numeric vector consisting of ones and zeros. The length of
          'cl' must be equal to the number of observations. If 'cl'
          consists of zeros and ones, Wilcoxon Rank Sums are computed.
          If 'cl' contains only ones, Wilcoxon Signed Rank Statistics
          are calculated.

    rand: Sets the random number generator into a reproducible state.
          Ignored if Wilcoxon rank sums are computed, or 'X' contains
          no zeros.

_D_e_t_a_i_l_s:

     If there are ties, then the ranks of the observations belonging to
     the same group of tied observations will be set to the maximum
     rank available for the corresponding group.

_V_a_l_u_e:

     A numeric vector containing Wilcoxon rank statistics for each row
     of 'X'.
