homals package and core loop
...using OpenMP or Grand Central Dispatch.
For ordinal variables this requires some alternative quadratic
programming
routines to be linked in (which could then also become part of the
isotone package).
In addition the basic homals code will have object (individual) weights
(minor addition) and the prehom routines (from the jacobi package) will
be added. Because of the use of B splines the variables in homals will
no longer be all factors, some can now be numerical ("continuous").
Otherwise the package will keep its many analysis options (multi-set
non-metric canonical analysis,
non-met...
