Use xcount
to determine the exact number of tables (i.e., genotype numbers) for a given set of allele counts. This method enumerates all tables, and is best when the total number is less than 10^10 or so. This function is mostly called by hwx.test
rather than directly by the user. If the number of tables is too large to enumerate with this method, use acount
for an approximation.
