Dear r-helpers,

..apart from the discussion about "observed power": can somebody give me an exan how hpower works? Currently I calculate sample-sizes with power.t.test and external programs, and i wonder if I would really need these additional stuff. "hpower" seems to be powerful, but also a little bit cryptic, at least at the first sight...

thanks
PM
