R help - Feb 2012 - Post hoc test for lm() or glm() ?

Hi R-helpers,

TukeyHSD() works for models fitted with aov(), but could anyone point
me to a function that performs a similar post hoc test for models
fitted with lm() or glm()?

Thanks in advance,

Mark

The R multcomp package provides one general approach to multiplicity
correction.  For general contrasts in lm and glm, the rms package's ols and
Glm functions make this even easier to use.

The glht function in the multcomp package is what you are looking for.
There are additional examples in the ?MMC help file in the HH package.
