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

     Mine frequent itemsets with the Eclat algorithm. This algorithm
     uses simple intersection operations for equivalence class
     clustering along with bottom-up lattice traversal.

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

     eclat(data, parameter = NULL, control = NULL)

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

    data: object of class 'transactions' or any data structure which
          can be coerced into 'transactions' (e.g., binary 'matrix',
          'data.frame').

parameter: object of class 'ECparameter' or named list (default values
          are: support 0.1 and maxlen 5)

 control: object of class 'ECcontrol' or named list for algorithmic
          controls.

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

     Calls the C implementation of the Eclat algorithm by Christian 
     Borgelt for mining frequent itemsets.

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

     Returns an object of class 'itemsets'.
