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()
o Converted the package to roxygen2 documentation, correcting some infelicities with S3 methods o Added an extended README example. o fix link to genridge paper PDF
o a maintenance release, correcting a problem with an in one .Rd file
o Remove references to ElemStatLearn, now defunct
o bump package version, preparing to move to Github
o Use rgl:: in calls to rgl package for CRAN o Fixed long lines in .Rd files
o Added contourf()
o Minor tweaks to plot3d.ridge o Added biplot.ridge method for symmetry, showing the PCA vectors in variable space o Added examples to ridge.Rd using data(manpower, package=“bestglm”) o Added Manpower data
o Made ridge() an S3 generic with formula and default methods o Fixed labels problems in biplot.pcaridge and plot3d.ridge o Added Detroit data with examples showing most methods
o Fixed order of classes in pca.ridge o Made plot3d an S3 generic; added plot3d.pcaridge and plot.pcaridge o Added biplot.pcaridge() to draw variable vectors on a plot.pcaridge() plot o Added options to precision.* for greater flexibility o Added GCV computation to ridge() o Added which.lambda to select ellipses in plot.ridge(), plot3d.ridge() etc. o Added labels argument to plot.ridge() and fixed pairs.ridge for this.
o Added plot3d.ridge() using rgl, completing the main stages in visualization methods for ridge-like problems
o Added precision.ridge() method for measures of precision and shrinkage o Added vif.ridge() method, extending the car S3 generic for ridge objects o Now Depends: car
o Added Acetylene data o Added vcov.ridge() method
o Fixed Authors@R in DESCRIPTION
o Added NAMESPACE o Initial package version, released to R-Forge o Added pca.ridge
