We investigate in detail the effects of R-parity lepton number violation in the minimal supersymmetric standard model (MSSM) on top-quark pair production via both ${e}^{\ensuremath{-}}\ensuremath{-}{e}^{+}$ and $\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}$ collision modes at the linear colliders. We find that with the present experimental constrained $R/$ parameters, the effect of $R/$ interactions on the processes ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}t\overline{t}$ and ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\gamma}\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\gamma}}t\overline{t}$ could be significant and may reach $\ensuremath{-}30%$ and several percent, respectively. Our results show that the $R/$ effects are sensitive to the c.m. system energy and the relevant $R/$ parameters. However, they are not sensitive to squark and slepton masses when ${m}_{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{q}}g~400\mathrm{GeV}$ (or ${m}_{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{l}}g~300\mathrm{GeV})$ and are almost independent of $\mathrm{tan}\ensuremath{\beta}.$
