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

     This function compute the scaled log-ratios from raw probe
     intensities, as done by Nimblegen for normalization.

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

     nimblegenNorm(myRG, ...)

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

    myRG: Object of class 'RGList'

     ...: further arguments passed on to 'tukey.biweight'

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

     Nimblegen provides scaled  log-ratios as normalized values for the
     probes. log.ratio = log2(R)-log2(G) scaled.ratio = log.ratio -
     tukey.biweight(log.ratio)

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

     Return an 'MAList', with the M slot of the list holding the scaled
     log ratios.
