In this paper we consider the k-plane Nikodym maximal estimates in the variable Lebesgue spaces Lp(·)(Rn). We first formulate the problem about the boundedness of the k-plane Nikodym maximal and show that the maximal estimate in Lp(Rn) is equivalent to that in Lp(·)(Rn) for p(·)∈LH0∩N∞. So, the optimal Nikodym maximal estimate in Lp(·)(R2) follows from Cordoba's estimate.
