I suspect that the reason no one has yet offered ideas is that the  
question is a bit (well, OK, ... extremely) vague. You have not  
described in any detail what the question might be. That said there  
are several functions for power calculations in the context of  
survival analysis in the Hmisc package, some of which probably reduce  
to simple cases (such as the Wilcoxon rank sum test) in the absence of  
censoring.
