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

     lcvplot(..., alpha)

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

     ...: arguments to the `lcv', `locfit' functions.

   alpha: Matrix of smoothing parameters. The `aicplot' function loops
          through calls to `lcv', using each row of `alpha' as the
          smoothing parameter in turn. If `alpha' is provided as a
          vector, it will be converted to a one-column matrix, thus
          interpreting each component as a nearest neighbor smoothing
          parameter.

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

     An object with class `"gcvplot"', containing the smoothing
     parameters and LCV scores. The actual plot is produced using
     `plot.gcvplot'.

_S_e_e _A_l_s_o:

     `locfit', `locfit.raw', `gcv', `lcv', `plot.gcvplot'

_E_x_a_m_p_l_e_s:

     data(ethanol)
     plot(lcvplot(NOx~E,data=ethanol,alpha=seq(0.2,1.0,by=0.05)))
