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

table(exclude = NULL) always includes NA
I stand corrected. The part "If set to 'NULL', it implies 'useNA="always"'." is even in the documentation in R 2.8.0. It was my fault not to check carefully.
I wonder, why "always" was chosen for 'useNA' for exclude = NULL.
Why exclude = NULL is so special? What about another 'exclude' of length zero, like character...

table(exclude = NULL) always includes NA
The quirk as in table(1:3, exclude = 1, useNA = "ifany") is actually somewhat documented, and still in R devel r71104. In R help on 'table', in "Details" section:
It is best to supply factors rather than rely on coercion. In particular, ?exclude? will be used in coercion to a factor, and so values (not levels) whic...

a fast table() for the 1D case
Hi,
table1D() below can be up to 60x faster than base::table() for the 1D
case. Here are the detailed speedups compared to base::table().
o With a logical vector of length 5M: 11x faster
(or more if 'useNA="always"')
o With factor/integer/numeric/character of length 1M and 9 levels
(or 9 distinct values for non-factors):
- factor: 60x faster
- integer/numeric vector: 12x faster
- character vector: 2.4...

or
is.na(a) <- as.logical(match(a0, c(exclude,NA), nomatch=0L)) .
The parallel code
is.na(a) <- match(a0, exclude, nomatch=0L)
is to be treated similarly.
Example that gives wrong result in R devel r71225:
table(3:1, exclude = 1)
table(3:1, exclude = 1, useNA = "always")

This came from a local user who wanted to remove one particular response
from some tables, but also wants to have NA always reported for data
checking purposes.
I don't think the above is what anyone would want.

Emacs function argument hints
...standard R text editor
for Mac OS. In the Mac OS editor when you start typing a function, the
possible arguments for that function appear at the bottom of the window.
E.g. if you type "table( " before you finish typing you can see at the
bottom of the window:
table(..., exclude = if (useNA == "no") c(NA, NaN), useNA = c("no",
"ifany", "always"), dnn = list.names(...), deparse.level = 1)

xtabs and NA
...ues using xtabs. Please find a minimal example below, it's also on
R-pubs [1]. Tested with R 3.1.2 and R-devel r67720.
It doesn't seem to be documented explicitly that it's not supported.
From reading the code [2] it looks like the relevant call to table()
doesn't set the "useNA" parameter, which I think is necessary to make
NAs show up in the result.
Am I missing anything? If this a bug -- would a patch be welcome? Do we
need compatibility with the current behavior?
I'm aware of workarounds, I just prefer xtabs() over table() for its
interface.
Thanks.

Actually, I would like to give a list of n characters that would be used to
