     hold a list of Lines objects; each Lines object holds a list of
     Line (line) objects.

_S_l_o_t_s:


     '_l_i_n_e_s': Object of class '"list"'; list members are all of class
          Lines-class

     '_b_b_o_x': Object of class '"matrix"'; see Spatial-class 

     '_p_r_o_j_4_s_t_r_i_n_g': Object of class '"CRS"'; see CRS-class

_E_x_t_e_n_d_s:

     Class '"Spatial"', directly.

_M_e_t_h_o_d_s:


     [ 'signature(obj = "SpatialLines")': select subset of (sets of)
          lines; NAs are not permitted in the row index

     _c_o_o_r_d_i_n_a_t_e_s value is a list of lists with matrices 

     _p_l_o_t '\signature(x = "SpatialLines", y = "missing")':  plot lines
          in SpatialLines object

     _l_i_n_e_s '\signature(x = "SpatialLines")':  add lines in SpatialLines
          object to a plot
