R help - Sep 2010 - confidence intervals around p-values

Dear all

I wonder if anyone has heard of confidence intervals around p-values...

Any pointer would be highly appreciated.

  No, and my reflex is that it seems like a bad idea.
  If you are using p-values as an index of effect size (e.g. translating
a t- or Z-score into a p-value), why not calculate the confidence interval
on the effect size?
  This is off-topic for the group (not an R question), but if you
gave a sense of the problem you were trying to solve you might get
some answers.

That doesn't really make sense.  p-values are statistics, not 
parameters.  You would compute a confidence interval around a population 
mean because that's a parameter, but you wouldn't compute a confidence 
interval around the sample mean:  you've observed it exactly.
