   Residual factor for all reflections satisfying the
   resolution limits established by _refine_ls_d_res_high and
   _refine_ls_d_res_low. This is the conventional R
   factor. See also _refine_ls_wR_factor_ definitions.

       sum | F(obs) - F(calc) |
   R = ------------------------
             sum | F(obs) |

   F(obs)  = the observed structure-factor amplitudes
   F(calc) = the calculated structure-factor amplitudes

   and the sum is taken over the specified reflections

The permitted range is 0.0 -> infinity
