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

     Sets to zero the phase of time-frequency transform when modulus is
     below a certain value.

     cleanph(tfrep, thresh=0.01, plot=TRUE)

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

  thresh: (relative) threshold. 

    plot: if set to TRUE, displays the maxima of cwt on the graphic
          device.
