Erratum to: "Nuclear Effects on R=\sigma_L/\sigma_T in Deep-Inelastic   Scattering" Phys.Lett. B475(2000)386
  This erratum revokes the main conclusion of a Letter that reported measurements of cross sections for deep-inelastic scattering (DIS) of leptons on $^3$He and $^{14}$N targets, expressed as ratios of $\sigma_A / \sigma_D$ to the cross section on the deuterium target.
