[R] power 2x3 exact test

[Bingshan Li]

Hi, all,

I am wondering if there is an algorithm for calculating power of 2x3  
table using Fisher exact test. There is one (algorithm 280) for 2x2  
Fisher exact test but I couldn't find one for 2x3 table. If we are  
not lucky enough to have one, is there any other way to calculate  
exact power of 2x3 table? The reason why I want exact power is  
because some cells are assumed to be very small and chi square  
approximation is not valid.

Thanks!
