The NEWS file for R-1.7.0 says:
table() now allows exclude= with factor arguments (requested by
Michael Friendly).
But in a recent R-1.7.1beta:
> test <- c(1,2,3,4,5,1,2,3,4,5,NA,NA,1,2,3,4,5)
> table(test)
test
1 2 3 4 5
3 3 3 3 3
> table(test, exclude=NULL)
test
1 2 3 4 5 <NA>
3 3 3 3 3 2
> table( as.factor(test), exclude=NULL)
1 2 3 4 5
3 3 3 3 3
so this seems not to work?
What is strange is that this seems to work in
example(table).
