Using an isospin-dependent parameterized equation of state (EOS), we study the relation between $R$ and $\\Lambda$ of neutron stars and its dependence on parameters of symmetry energy $E_{\\rm sym}$ and EOS of symmetric nuclear matter $E_0$ when the mass is fixed as $1.4$ $M_\\odot$, $1.0$ $M_\\odot$, and $1.8$ $M_\\odot$, respectively.
