We present an analysis of a devised sample of rotation curves (RCs), with the aim of checking the consequences of a modified f(R) gravity on galactic scales. Originally motivated by the mystery of dark energy, this theory may explain the observed non-Keplerian profiles of galactic RCs in terms of a breakdown of Einstein general relativity. We show that, in general, the power-law f(R) version could fit the observations well, with reasonable values for the mass model parameters. This could encourage further investigation into R-n gravity from both observational and theoretical points of view.
