[R] Multiple comparisons when interacction

[Jorge Lampurlanes Castel]

Yes, it can be done.  It is not currently easy because multcomp doesn't
have the syntax yet.  Making this easy is on Torsten's to-do list for the
multcomp package.

See the MMC.WoodEnergy example in the HH package.  The current version on
CRAN
is HH_1.17.  Please see the discussion of this example in R-help:
