The following is symmetric, and suitable for comparing two data sets, or two model amplitudes:

$[itex] R=\frac{\sum_{hkl}\vert F_{hkl}^{i}-F_{hkl}^{j}\vert}{\sum_{hkl} 1/2 (F_{hkl}^{i}+F_{hkl}^{j})} + R=\frac{\sum_{hkl}\vert F_{hkl,i}-F_{hkl,j}\vert}{0.5\sum_{hkl} F_{hkl,i}+F_{hkl,j}}$

[/itex]
for amplitudes, and analogously for intensities:

for amplitudes, and analogously for intensities. This R value is called R<sub>scale</sub>, as far as I know.
