_D_e_s_c_r_i_p_t_i_o_n:

     this class holds data consisting of (sets of lines), where each
     set of lines relates to an attribute row in a data.frame

     can be created by the function SpatialLinesDataFrame

_S_l_o_t_s:

_M_e_t_h_o_d_s:

     Methods defined with class "SpatialLinesDataFrame" in the
     signature:

     [ 'signature(x = "SpatialLinesDataFrame")': subset rows or
          columns; in case of row subsetting, the line sets are also
          subsetted 

     _c_o_o_r_d_i_n_a_t_e_s 'signature(obj = "SpatialLinesDataFrame")': retrieves
          a list with lists of coordinate matrices 

     _s_h_o_w 'signature(object = "SpatialLinesDataFrame")': print method 

     _p_l_o_t 'signature(x = "SpatialLinesDataFrame")': plot points

     _l_i_n_e_s 'signature(object = "SpatialLinesDataFrame")': add lines to
          plot

     _s_u_m_m_a_r_y 'signature(object = "SpatialLinesDataFrame")': summarize
          object
