Hi everyone,

When I tried to use chisq.test or fisher.test in bioconductor, I always got
higher p-value than that with other sources.

For example, I have two observed values 15 and 5 and two expected values 10
and 10.

Using other sources such as Excel from Microsoft, I got p-value 0.025.

However, in bioconductor,

*chisq*.*test*(x=matrix(c(15,5,10,10),nc=2),correct=FALSE)

or

 *chisq*.*test*(x=matrix(c(15,10,5,10),nc=2),correct=FALSE)

p-value always is 0.1025.

Did I do something wrong?

Please tell me why there is big difference in p-value. How can I get low
p-value in bioconductor?

Thanks,

Hai-Ri
