RFC: tapply(*, ..., init.value = NA)
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 xtabs() formula,

Undefined behavior of head() and tail() with n = 0
Hi all,
The documentation for head() and tail() describes the behavior of
these generic functions when n is strictly positive (n > 0) and
strictly negative (n < 0). How these functions work when given a zero
value is not defined.
Both GNU command-line utilities head and tail behave differently with +0 and -0:
