New function surrogate for returning the surrogate response values used in calculating the surrogate-based residuals. The surrogate response values can be useful for checking the proportionality assumption of fitted cumulative link models, among other things.
Jittering (on both the probability scale and the response scale) is now available for fitted cumulative link models based on packages MASS, ordinal, rms, and VGAM (#18).
Added support for vector generalized additive models from the VGAM package (i.e., objects of class "vgam").
New data sets df4 and df5 for illustrating various uses of the surrogate residual for diagnostics an ordinal regression models.
