useNA = c("no", "ifany", "always"), dnn = list.names(...), deparse.level = 1)
table(..., exclude = if (useNA == "no") c(NA, NaN), 
useNA = c("no", "ifany", "always"), dnn = list.names(...), deparse.level = 1)

ff factors or ff integers

table.ff uses the cross-classifying factors to build a contingency table of the counts at each combination of factor levels. If ... does not contain factors, unique.ff will add a levels attribute to the non-factors.
