  The nontrivial structure of the neutrino mass matrix, suggested by the recent
Super-Kamiokande results and data from other neutrino experiments, can be
reproduced in R-parity-violating supersymmetric theories. This requires sets of
products of R-parity-violating trilinear couplings to take appropriately chosen
values. It is shown that the existing constraints on these couplings are
satisfied by these choices.
