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

     performs K separated multivariate analyses of an object of class
     'ktab'  containing K tables.

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

     sepan(X, nf = 2)
     plot.sepan (x, mfrow = NULL, csub = 2, ...)
     summary.sepan (object, ...)
     print.sepan (x, ...)

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

       X: an object of class 'ktab'

      nf: an integer indicating the number of kept axes for each
          separated analysis

x, object: an object of class 'sepan'

   mfrow: a vector of the form "c(nr,nc)", otherwise computed by a
          special own function 'n2mfrow'

    csub: a character size for the sub-titles, used with
          'par("cex")*csub'

     ...: further arguments passed to or from other methods

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

     The function plot on a 'sepan' object allows to compare inertias
     and structures between arrays. In black, the eigenvalues of kept
     axes in the object 'sepan'.

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

     returns a list of class 'sepan' containing : 

    call: a call order

tab.names: a vector of characters with the names of tables

     blo: a numeric vector with the numbers of columns for each table

    rank: a numeric vector with the rank of the studied matrix for each
          table

     Eig: a numeric vector with all the eigenvalues

      Li: a data frame with the row coordinates

      L1: a data frame with the row normed scores

      Co: a data frame with the column coordinates

      C1: a data frame with the column normed coordinates

      TL: a data frame with the factors for Li L1

      TC: a data frame with the factors for Co C1
