SUGGESTION: Settings to disable forked processing in R, e.g. parallel::mclapply()

Mostly, yes. But it says nothing about fork's copy-on-write and memory
overcommitment, and that this means that it may work nicely or fail
spectacularly depending on whether, e.g....

Rtools and R 4.0.0?
Hello,
Has a decision been made yet as to whether R 4.0.0 on Windows is going
to be built using the new gcc8 toolchain (described at
https://cran.r-project.org/bin/windows/testing/rtools40.html)?
>From the sidelines, I can see that the toolchain is being used to

Alternative for wildcard gnu extension in Makevars
One other solution that's only a little crazy: you could have a R
function within your package that generates the appropriate (portable)
Makevars, and within the package `configure` script call that
function. For example"
R --vanilla --slave -e "source('R/makevars.R'); makevars()"
And that 'makevars()' function could generate portable

writeLines argument useBytes = TRUE still making conversions
Of course, right after writing this e-mail I tested on my Windows
machine and did not see what I expected:
> charToRaw(before)
[1] c3 a9
> charToRaw(after)
[1] e9
so obviously I'm misunderstanding something as well.

This may be intentional, but the behavior seems surprising and could
be responsible for the behavior outlined earlier.

New R function is.nana = is.na & !is.nan
...g to kindly request new R
function so NA_real_ can be more easily detected.
Currently if one wants to test for NA_real_ (but not NaN) then extra
work has to be done: `is.na(x) & !is.nan(x)`
Required functionality is already at C level so to address my request
there is not that much to do.
Kevin Ushey made a nice summary of current R C api in:

But seems like a useful topic for discussion.

lapply (and friends) with data.frames are slow
Hey guys,
I noticed something curious in the lapply call. I'll copy+paste the
function call here because it's short enough:
lapply <- function (X, FUN, ...)
{
FUN <- match.fun(FUN)
if (!is.vector(X) || is.object(X))
X <- as.list(X)
.Internal(lapply(X, FUN))
}
Notice that lapply coerces X to a list if the !is.vector || is.object(X)
check passes.
Curiously,

Thanks, I can now reproduce and it is a bug that is easy to fix, I will

Fyi it can be reproduced simply by running these two lines in Rgui:
list()
