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

     A collection and description of generic functions  to concatenate,
     to sort and to reorder 'timeDate' aobjects 

     The functions are:

       'c.timeDate'       Concatenates 'timeDate' objects,
       'rep.timeDate'     Replicates a 'timeDate' object,
       'sort.timeDate'    Sorts a 'timeDate' object,
       'sample.timeDate'  Resamples a 'timeDate' object,
       'unique.timeDate'  NMakes a 'timeDate' object unique,
       'rev.timeDate'     Reverts  a 'timeDate' object.

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

     ## S3 method for class 'timeDate':
     c(..., recursive = FALSE)
     ## S3 method for class 'timeDate':
     rep(x, ...)
     ## S3 method for class 'timeDate':
     sample(x, ...)
     ## S3 method for class 'timeDate':
     sort(x, ...)
     ## S3 method for class 'timeDate':
     unique(x, ...)
     ## S3 method for class 'timeDate':
     rev(x)

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

recursive: [c] - 
           a logical. If recursive  is set to 'TRUE', the function 
          recursively descends through lists combining all their
          elements  into a vector.  

       x: an object of class 'timeDate'. 

     ...: arguments passed to other methods. 

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

     'c'
      'rep'
      'sample'
      'sort'
      'unique'
      'rev' 
      these are functions to concatenate, to replicate, to resample, to
     sort, to make unique, and to revert 'timeDate' objects. The
     functions return an object of class '"timeDate"'.

_A_u_t_h_o_r(_s):

_S_e_e _A_l_s_o:

     We also recommend to inspect the help pages for the POSIX time and
     date  class, '?Dates', and the help pages from the contributed R
     packages 'chron' and 'date'.
