[Rd] power analysis for sample size calculations

[Marjo en Edwin]

Dear all,

The existing R packages for doing power analyses (pwr, hpower) seem 
quite basic/limited, compared to the power analyses implemented in the 
UnifyPow SAS module.

I wondered if there are people working on power analyses for a broader 
range of statistical tests than pwr and hpower cover or maybe on 
implementing UnifyPow functionality in R. I would like to give a shot at 
it, but I would like feedback if anyone is already working on this 
(maybe I can help) or if anyone would advise against it.

Greetings,
Edwin Commandeur
