This is just provided for convenience and to illustrate the changes. It is
not guaranteed to be complete, and is liable to be withdrawn. Users who
were relying on the previous undocumented format are advised to upgrade
their code to use the new format, which uses model frames and model design
matrices in the standard format used in version 1.4, based on
model.frame and model.matrix.
