     See the individual functions for specific implementation and
     argument details.  Details of the underlying TTR implementations
     can be found in 'TTR'.

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

     Called for its side effects, an object to class 'chobTA' will be
     returned invisibly.  If called from the R command line the method
     will draw the appropriate indicator on the current chart.

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

     Jeffrey A. Ryan

_R_e_f_e_r_e_n_c_e_s:
