Here is my table

> tt
    A   B
1 297 398
2 470 376
3  30  23
4   3   3
5   0   0

b/c two cells are zero, I can't use chisq.test() in R which gives the
following output;


> chisq.test(tt)

        Pearson's Chi-squared test

data:  tt
X-squared = NaN, df = 4, p-value = NA

Warning message:
Chi-squared approximation may be incorrect in: chisq.test(tt)

What function should I use then? Any suggestion?
