In the general picture of high order theories of gravity, recently, the R -1 theory has been analyzed in two different frameworks. In this letter a third context is added, considering an explicit coupling between the R -1 function of the Ricci scalar and the matter Lagrangian. The result is a non-geodesic motion of test particles which, in principle, could be connected with Dark Matter and Pioneer anomaly problems.
