Dear R users,

I'd like to announce version 2.0-0 of the effects package, which is now on
CRAN. The package constructs graphical and tabular "effect displays," e.g.,
of interactions, for several kinds of models. These displays are
generalizations of "adjusted" means in linear models. 

The major addition to the package is the ability to display terms in
multinomial and proportional-odds logit models (using results described in
Fox, J. and R. Andersen (2006), "Effect displays for multinomial and
proportional-odds logit models," Sociological Methodology 36, 225-255; the
original package was described in Fox, J. (2003), "Effect displays in R for
generalised linear models," Journal of Statistical Software 8:15, 1-27.)

The new version of the package is co-authored with Jangman Hong.
