Subject: 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?

Any other suggestions please?

Thanks in advance,
