table() and setting useNA to be there by default?

Good morning, Is there a way to get table() to default to including NAs - as in... table(..., useNA='ifany') or table(..., useNA='always') or table(..., exclude=NULL) ? I can't see a way under table() or options() or searching the archives (probably using the wrong keyword?).
t1 <- c(1,2,3,3,3,2,NA,NA,NA,NA) table(t1)
t1 1 2 3 1 2 3 I keep forgetting to allow for NAs and I was bitten *again* this morning... ideally I'd like to be able to set a default in my profile so that table(t1) will actually do table(t1, exclude=NULL) or table(t1, useNA='ifany') I could say something like..
tab1 <- function(t, ...) { table(t, ..., useNA='ifany') }
tab1(t1)
t 1 2 3 <NA> 1 2 3 4 but this names it as 't' instead of 't1' which is ugly?
How about tab1 <- function(...) table(..., useNA='ifany') -Peter Ehlers
Any other suggestions please? Thanks in advance, Sean O'Riordain Dublin Ireland
