Thanks John,

I will try to perform the implementation myself using the updated

Has anyone pointers to efficient algorithm for two-sided 2x2 Fisher
exact (or Barnard) test, able to deal with mix of small and large
cell counts ( 0 and ~ 10,000) ?
Large cell counts are typically a problem for the classical factorial


Cheers !
