Test of symmetry for contingency tables


I am looking for a function, that could help me perform the "test of symmetry for contingency tables" (my table is 3x3, so I can't you McNemar's test).

I found nominalSymmetryTest, which is exact. But I need an a test, that only approximates the test statistics (based on chi^2 statistics). The exact test takes too long.

Is there a function, that could help me?

Thanks in advance!
