_D_e_s_c_r_i_p_t_i_o_n:

     This function gets information from the c component of an
     'irregwd.objects' an irregularly spaced wavelet decomposition
     object. 

     Note that this function is _not_ the same as 'accessC' which
     obtains father wavelet coefficients from an 'wd' class object.

_U_s_a_g_e:

     accessc(irregwd.structure, level, boundary=FALSE)

_A_r_g_u_m_e_n_t_s:

irregwd.structure: Irregular wavelet decomposition object from which
          you wish to extract parts of the 'c' component from.

   level: The level that you wish to extract. This value ranges from 0
          to the 'nlevels'(irregwd.structure)-1.

boundary: If this argument is T then all of the boundary correction
          values will be returned as well (note: the length of the
          returned vector may not be a power of 2). If boundary is
          false, then just the coefficients will be returned. If the
          decomposition (or reconstruction) was done with periodic
          boundary conditions then this option has no effect.

_D_e_t_a_i_l_s:

     The 'irregwd' function produces a irregular wavelet decomposition
     (reconstruction) structure. 

     The 'c' component is stored in a similar way to the C and D
     vectors which store the father and mother wavelet coefficients
     respectively. Hence to access the information the accessc function
     plays a similar role to 'accessC' and 'accessD' functions.

_V_a_l_u_e:

     A vector of the extracted data.
