Apologies. Clearly I misunderstood the R implementation. My parsing of 
the fisher.test code (influenced by having just read the Campbell 
article) lead me to erroneously conclude that it was only applicable to 
2x2 tables. I see now that the error message says "_at_least_ 2 rows 
and columns" and that the error check is an inquality.
