   Residual factor R for reflections that satisfy the resolution
   limits established by _refine_ls_shell.d_res_high and
   _refine_ls_shell.d_res_low and the observation limit
   established by _reflns.observed_criterion, and that were used
   as the working reflections (i.e. were included in the
   refinement) when the refinement included the calculation of
   a 'free' R factor. Details of how reflections were assigned
   to the working and test sets are given in _reflns.R_free_details.

       sum|F~obs~ - F~calc~|
   R = ---------------------

   F~obs~  = the observed structure-factor amplitudes
   F~calc~ = the calculated structure-factor amplitudes

   sum is taken over the specified reflections
