Last week, we've talked here about "xtabs(), factors and NAs",
-> https://stat.ethz.ch/pipermail/r-devel/2017-January/073621.html
In the mean time, I've spent several hours on the issue
and also committed changes to R-devel "in two iterations".
In the case there is a *Left* hand side part to xt
mode(ans[[1]]))
else NA
.
A colleague proposed to use the shorter argument name 'default'
instead of 'init.value' which indeed maybe more natural and
still not too often used as "non-first" argument in FUN(.).
Thank you for the constructive feedbac
advantages are not even getting close to counter-weigh the drawbacks.

Thank you very much!
They have been applied to the R-devel and R-pa
e mode (0 for raw) is automatically used."
After some thought (and experiments), I have reverted and no
longer use if(missing). You are right that it is not needed
(and even potentially confusing) here.
Changes are in svn c72106.

Last but not least :
If you are not afraid of +/- Inf, but really only of NA/NaN's (as the OP said),
then note that "THE manual" (= "Writing R Extensions") does mention
ISNAN(.) almost in the same place as the first occurence of
R_FINITE(.).

their
versions of R provide (concise and not hard to read) patches to
the source of R, we'd probably gratefully accept them..

Now this is an e-mail that *REALLY* does not fit to the R-devel
mailing list ... even

bug report, and your proposal to make the simple case rep(s, list(7))
work as previously seems ok to me.
However, for all this, we will concentrate on R-devel (to become
R 3.4.0).
