- McNemar with unequal sample sizes

Christian Montel

i need to test the equality of proportions in a paired case, like here:
after before
        + -
+ 10 14
- 5 53

So usually i use the mcnemar.test(stats).

Due to mortality, I now got the problem that my sample sizes in both
factors are not equal any more -- there are less cases in the "after"
condition. I already learned that Ekbohm (1982) and Marascuilo adressed
the problem conceptually, but I'm not that good at writing my own

Can anyone give me a hint what function/test/package in R to use?

Thank you very much for your help,
