Due to lazy evaluation, the order of operations can be pretty random in R.
Actually, some operations may not be performed at all, sometimes.
The following program illustrates the issue:
test1=function(x,y) {}
test2=function(x,y) {x;y}
test3=function(x,y) {y;x}
alpha="hello"
test1(alpha <- 1,
Running things in various forms of parallel opens up all kinds of issues.
Currently, programs that use forms like "threads" often need to carefully
protect any variables that can be changed using things like locks.
So what would they do in the scenario being discussed? Would they need to
It could be that the two sides of * are run in parallel in the future and maybe
not having a guarantee would simplify implementation?

Does anyone have a case where this construct has a valid use?
Didn't Python add a := operator recently that might be intended more for
such uses as compared to using the standard assignment operators? I wonder
if that has explicit guarantees of what happens in such cases, but that is
outside
I agree and personally never do this but I would still like to know if it
is guaranteed behavior or not.

Dear Bioconductor support team,
since a couple of years my alsace package is part of Bioconductor. For
some time, however, active development has stopped, and I do not have
the idea that it will pick up in the near future. I would like to
withdraw the package from Bioconductor, and have it
It depends on what you mean by logo. If you created an image or sticker of
some sort with the package name, you are free to change this as Bioconductor
does not utilize that information currently on our site or landing pages.
There are no restrictions currently for changing a package logo
Dear R developers,
R makes some functions interruptible, thanks to a call to R_CheckUserInterrupt.
Simple arithmetic operations can be interrupted avoiding freezes when using
huge arrays (e.g. length > 1 billion).
But many operations, such as matrix multiplication, are not interruptible. I

Hi bioc-devel,
I was wondering if it's possible to change the *logo *of a package after it
has been submitted to Bioconductor. So far, my package logo is used in
my *shiny

review in Bioconductor next week.
