In SAS, for a two-way (or 3-way, stratified) table, the CMH option in SAS PROC FREQ gives 3 tests that take ordinality of the factors into account, for both variables, just the column variable
or neither.   Is there an equivalent in R?
The mantelhaen.test in stats gives something quite different (a test of conditional independence for
*nominal* factors in a 3-way table).

e.g. I'd like to reproduce:
*-- CMH tests;
proc freq data=sexfun order=data;
 weight count;
 tables husband * wife / cmh chisq nocol norow;
 run;
