I've uploaded to CRAN a new package called effects. The package contains
functions for tabular or graphical display of terms in a linear or
generalized linear model, and is particularly suitable for models that
contain terms -- such as main effects and interactions, or polynomial
regressors -- related by marginality (hierarchy). A draft paper describing
the package is located at
