[R] Mantel-Haenszel for 2x2

[Dr. Jeff Miller]

Rob,

I had tried that but mhor requires 3 variables (i.e., a conditional test). I
didn't think to just create a third variable...vector of 1's.  Now it works
fine.

Thanks!

Jeff

Hi all,



Does anyone know if an R function for the Mantel-Haenszel chi-square for a
2x2 table exists?  I've also seen it called the randomization Q statistic.

Note that I'm not looking for the Cochran-Mantel-Haenszel.I did see that out
there as cmh.test.



Thanks in advance,

Jeff
