In the context of quantum chromodynamics (QCD), an analysis is presented of a compilation of eN deepinelastic scattering data taken at SLAC. Included are data for F₂ᵉᵖ, F₂ᵉᵈ, F₂ᵉᵖ-F₂ᵉⁿ, and R. The interaction between the logarithmic scaling violation from αₛ and the power-law scaling violation from higher-twist terms is discussed. This interaction can affect the determination of the parameter Λ and can alter the predictions for the ratios of anomalous dimensions. Furthermore, we show that, in the context of QCD, higher-twist terms may be able to account for the observed value of R=σLσT which appears to be anomalously large. Different experiments have made different assumptions for the value of R used in extracting F₂ from their data. We show that these differences can account for the discrepancies in the relative normalizations of F₂ from these experiments and also can have a significant effect on the value of Λ obtained.
