Hi Simon and all,
I'm pretty sure that you are correct about this. I think it is a
misconception to say that the fisher exact test is only for a 2 by 2 table.
It is presented that way in textbooks because, for a 2x2 table, it is easy
to perform. For larger tables, it becomes complex quickly due t
I posted this last night but I think I figured out the problem.
I checked on the underlying equation for the Fisher Exact Test for tables
greater than 2X2. It looks like I have an insane amount of factorials to be
multiplied.
Is that problem? Is it an overflow issue?

I just a ran a fisher.test on a 9x5 table and received the following message
Error in fisher.test(apaslg.t) : FEXACT error 30.
Stack length exceeded in f3xact.
This problem should not occur.
I agree. The problem should not occur.
I did some searching but only found other reports of th

I don't think the documentation in of itself is the core of the problem

I agree completely. Maybe it's time for an exhaustive manual (with weekly
downloadable updates, of course).
It would also be nice if it were cross-referenced. For example, to get what

Subject: [R] Mantel-Haenszel for 2x2
Hi all,
Does anyone know if an R function for the Mantel-Haenszel chi-square for a
2x2 table exist
Hi all,
Does anyone know if an R function for the Mantel-Haenszel chi-square for a
2x2 table exists? Ive also seen it called the randomization Q statistic.
Note that Im not looking for the Cochran-Mantel-Haenszel
I did see that out
there as cmh.test.
Thanks in advance,
Jeff
