This allows programmers to choose their implementation. Environments will be more efficient if there are a number of objects or if there are large static objects that will be passed to functions. Be very, very careful of using environments to pass around objects that might get altered. _O_b_j_e_c_t_s _f_r_o_m _t_h_e _C_l_a_s_s: A virtual Class: No objects may be created from it. _M_e_t_h_o_d_s: '_e_L_i_s_t(_e_S_e_t, _e_x_p_r_L_i_s_t)<-': A replacement method for 'eSet's. _A_u_t_h_o_r(_s): Biocore _S_e_e _A_l_s_o: 'list','environment','eSet' _E_x_a_m_p_l_e_s:
