genridge 0.7.1 (2024-11-07)

o Added links to gentalk.pdf o Improved README and fixed some examples o precision() result gains a class "precision" in preparation for a plot method o Implemented plot.precision() for plots shrinkage vs. variance, using various criteria o Fixed warning from ridge() related to contrasts o ridge() now collects the optimal criteria in a named list, which can be added in plot.precision()
