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

     Perform polar transforms on Illumina Golden Gate bead arrays

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

        RG2polar(object,trig=FALSE)
        polar2RG(object,trig=FALSE)

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

  object: SnpSetIllumina object

    trig: Logical, use geometric distance intensity. Otherwise use
          addition of intensities

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

     'RG2polar' transforms the 'R' and 'G' matrices to 'theta' and
     'intensity' matrices. Note that the intensity value is the sum of
     'R' and 'G' and not the geometric distance to the origin.

     'polar2RG' performs the reverse transformation

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

     This function returns an 'SnpSetIllumina' object.

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

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

     'SnpSetIllumina-class'

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

       data(chr17.260)
       data.polar<-RG2polar(chr17.260)
       plot(assayData(data.polar)$theta,assayData(data.polar)$intensity)
