From Clifton-Barrow spherically symmetric to axially symmetric solution
  in f(R)-gravity
  Starting from Clifton's spherical static solution for f(R)-gravity we can
derive axial symmetric solutions using a methods that takes the advantage of a
complex coordinate transformation. The new solutions are generated by applying
the Newman-Janis algorithm previously used to transform any static spherically
symmetric into axially metric in General Relativity
