[R] sample size/power calc packages

For various reasons, I spent part of my time today looking at sample
size and power calculation tools (don't ask, don't tell...).  This
seems to be one area that R is incredibly weak in (well, nearly all
stat packages, except perhaps specialized tools and SAS); sure, there
are a number of functions in various packages:

          base, statmod, Hmisc

Have I missed something?  (I would've expected at least one sequential
computation, or non-standard design, but apparently there are none, or
I missed it).  

I'd appreciate hearing about work that I've missed...

best,
-tony
