It is false. Code of function 'factor' in R 3.4.0
(https://svn.r-project.org/R/tags/R-3-4-0/src/library/base/R/factor.R) still
uses 'sort.list', not 'order'.

I would not want to change model.frame.default() currently as it's

In spite of all that *and*
the perennial drawback that a '...' will allow argument name
typos to go unnoticed
I agree you have a good argument nowadays, that median() should
be the same as many similar "basic statistics" R
out
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).

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

After some thought (and experiments), I have reverted and no

A colleague proposed to use the shorter argument name 'default'

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
t here... but of course we can continue
discussing here if you like.

cite above, the current
implementation was triggered by a nasty BLAS bug .. actually
also showing up only on some platforms, possibly depending on
runtime libraries in addition to the compilers used.
Do you have R code (including set.seed(.) if relevant) to show
on how to generate the large square matri

which is true, as well, and there
You are right (though picky). I have updated it now.
Thank you Henrik!

Shorter code *is* nicer than longer code, so I need a bit more
conviction why we should add more code for that special case ..

3/ The help page for I() could note what happens in the NULL case.
That would be the least work for everyone,
but at the moment, I tend to agree that '1/' is worth the pain to
have R's structure() become more consistent.

(In spite of Brian Ripleys good reasons against it, I'd still
aim for a *dynamic*, i.e. automatically increased list here).

As R is sophisticated enough to track leap seconds,
?.leap.seconds
we'd need to update our codes real soon now again:
https://en.wikipedia.org/wiki/Leap_second
(and those of you who want second precision in R in 2017 need to start
working with 'R patched' or 'R devel' ...)

is possibly only for you!
Note that I do *not* see problems on Linux (in ESS; did not try RStudio).
Please also indicate in which form you are running R.
Here it does depend if this is inside RStudio, ESS, the "Windows
GUI", the "Windows terminal", ...
