mantelhaen.test(x, exact=TRUE)

Exact conditional test of independence in 2 x 2 x k tables

data: x

S = 116, p-value < 2.2e-16

alternative hypothesis: true common odds ratio is not equal to 1
95 percent confidence interval:

0.0000000000 0.0001190186

sample estimates:

common odds ratio

0

Could this be some kind of memory overflow issue since some of the values are quite high? Or am I completely off here?

I would appreciate any help on this,

Florian
