R help - Sep 2002 - Contrasts in ANOVA table

Hello All,
Is there a way of producing an ANOVA table split into contrasts, thus showing
the contrasts sums of squares and associated p-values?

Thanks,
Martin.

Hi Martin,

One or more of the functions 'contrast.lm', 'estimable', and
'glh.test' from
the package 'gregmisc' may accomplish what you need:

contrast.lm              Compute (and test) arbitrary contrasts for
                         regression objects
estimable                Compute and test estimable linear functions of
                         the fitted coefficients (including contrasts) of
                         regression objects
glh.test                 Test a General Linear Hypothesis for a
                         Regression Model
