_D_e_s_c_r_i_p_t_i_o_n:

     These are objects of classes 

     'wd'

     They represent a decomposition of a function with respect to a
     wavelet basis. The function will have been interpolated to a grid
     and these objects represent the discrete wavelet transform 'wd'.

_D_e_t_a_i_l_s:

     To retain your sanity the C and D coefficients should be extracted
     by the 'accessC' and 'accessD' functions and inserted using the
     'putC' and 'putD' functions (or more likely, their methods),
     rather than by the `$' operator.

     One can use the 'accessc' function to obtain the 'c' component. 

     Mind you, if you want to muck about with coefficients directly,
     then you'll have to do it yourself by working out what the
     fl.dbase list means (see 'first.last' for a description.)

_G_E_N_E_R_A_T_I_O_N:

     This class of objects is returned from the 'irregwd' function.
     Some other functions that process these kinds of objects also
     return this class of object (such as 'threshold.irregwd'.)

_M_E_T_H_O_D_S:

     The 'irregwd' class of objects has methods for the following
     generic functions: 'plot', 'threshold',

_S_T_R_U_C_T_U_R_E:

     All components in a legitimate `irregwd' are identical to the
     components in an ordinary 'wd.object' with the exception of 'type'
     component and with the addition of the following component: 

_c Vector that aids in the calculation of variances of wavelet
     coefficients (used by 'threshold.irregwd').
