R help - Sep 2008 - Package implementing unconditional tests for comparing two binomials

Hello,

I am looking for a package implementing unconditional tests for comparing two 
binomials (Barnard's test or derivatives). As I am looking for rare
genotypes
within my groups, my number of subjects in one of the cells of the 2x2 table 
is often 2-4 resulting in a too conservative result by Fisher's exact test
due
to the discrete sample space of the test statistic. As I want to use this as a 
kind of filter for further investigations I am really interested in the 
additional power for 2x2 tables.

Any help or suggestions are really appreciated
Thank you very much

Thorsten
