[R-sig-Geo] Help with Haar's wavelet decomposition

    Hello all,
    Would know how to re-construct the original field
using the outputs from the dwt.2d function?
    I am getting the decomposition by entering:

    E.dwt <- dwt.2d (E, wf="haar", J=4)
    as outputs I get a set 12 of arrays: HH1, LH1,
HL1, HH2, LH2, HL2, ..., HL4.

   The question is, how to get back to E using the 12

   Any help will be appreciated.
