Yes I'd expect that too. But the **collapse** operation in paste()
A shorter reproducible example:
example(makeActiveBinding)

ls()
Both problems go away if you first do
compiler::enableJIT(2)
So looks like a bug in compiling the for loop.

Dear R-devel,
I'm curious why writeBin should always return NULL. Would anyone's code break
if we made it return the number of bytes written? I'm not sure how else I'm
supposed to use writeBin on a writable connection in non-blocking mode...
See attached.
Thank you,
Frederick

Not 0 (the analogu of Herve's desired behavior).

What about using the Wayback Machine archive ? The web archive should be
more stable than other links which also might disappear in the future.
E.g.
https://web.archive.org/web/20070610002602/http://www.herine.net/stat/software/dbinom.html

That's not the problem. The problem is that if you have

No, you are not missing anything, and you are right.

OK, so maybe one way to paraphrase:
For R, the boundedness of integer vectors is an implementation detail,
rather than a deeper mathematical fact that can be exploited for this
case.
One might also expect then that overflow wouldn't result in NA, but
rather automatically cast up to numeric? But t
Hi,
I stumbled upon a surprising behavior when using an active binding as a
loop index variable in R 4.0.0. In contrast, the behavior observed in R
3.6.1 is in line with my expectations.
Consider the code below:
makeActiveBinding("i",
function(value) {

Hi R developers,
There seems to be breaking change in base::order on Windows in

NEWS. Was the change intentional?
