_D_e_s_c_r_i_p_t_i_o_n:

     This function creates colors of class ``polarLUV''; a subclass of
     the virtual ``color'' class.

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

     polarLUV(L, C, H, names = NULL)

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

   L,C,H: these arguments give the L, C and H coordinates of the
          colors.  The values can be provided in separate `L', `C' and
          `H' vectors or in a three-column matrix passed as `L'.

   names: 

_D_e_t_a_i_l_s:

     The polarLUV space is a transformation of the CIE L*u*u* space so
     that the u and u values are converted to polar coordinates.  The
     radial component C measures chroma and the angular coordinate H is
     measures hue.

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

     An object of class ``polarLUV'' which inherits from class
     ``color.''

_A_u_t_h_o_r(_s):

     Ross Ihaka

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

     `RGB', `HSV', `XYZ', `LAB', `polarLAB', `LUV', `polarLUV'.

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

     ## Show the polarLUV space
     x = RGB(runif(1000), runif(1000), runif(1000))
     plot(as(x,"polarLUV"))
