_D_e_s_c_r_i_p_t_i_o_n:

     Used to compute coordinates for additional rows or additional
     factors in a multiple correspondence analysis.

_U_s_a_g_e:

     ## S3 method for class 'mca':
     predict(object, newdata, type = c("row", "factor"), ...)

_A_r_g_u_m_e_n_t_s:

  object: An object of class '"mca"', usually the result of a call to
          'mca'. 

 newdata: A data frame containing _either_ additional rows of the
          factors used to fit 'object' _or_ additional factors for the
          cases used in the original fit. 

    type: Are predictions required for further rows or for new factors? 

     ...: Additional arguments from 'predict': unused. 

_V_a_l_u_e:

     If 'type = "row"', the coordinates for the additional rows.

     If 'type = "factor"', the coordinates of the column vertices for
     the levels of the new factors.
