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')

Any other suggestions please?
