I think there is a memory error in the libcurl connection code that
typically happens when libcurl reads big chunks of data. This
potentially affects all code that use url() with the libcurl download

Hi All,
I realize that this is not a really nice reprex, but anyone has an
idea why a background R session would "remember" an interrupt (SIGINT)
on Unix?

FWIW topenv() is used in a couple of packages, although some of these
are false positives:

Just out of curiosity, do you think it is possible to make this

The new staged package installation shells out to the 'file' utility
on Unix systems:

Although 'file' is usually present on most Unix systems, it might be

Dear All,
If a package has dynamic manual pages (i.e. `\Sexpr{} macros), then R
CMD build installs the package, and (by default) creates the PDF
manual.
I understand that this is needed for build-time Sexprs. Could anyone
explain me why `R CMD build` needs to install the package if all the

This was some time ago:

So probably not hopeless, but I would think it is a lot of work.

So I am afraid you cannot use μm.

This should do.

Dear all,
is there a way to set R_MAKEVARS_SITE (or something else), so that R
finds Makevars.site for multiple archs?
AFAICT the only option is to put the arch directories in R.home(). But
I might be missing something.
My goal is to set different make variables for 32-bit and 64-bit R on
Window
FWIW man/figures/logo.png is picked up by pkgdown web sites, and also
by roxygen if you have a man page for the package itself.

The patch below adds support for custom HTTP headers in
download.file() and url().
My main motivation for this is performing basic http authentication.
Some web sites do not support embedding the credentials into the URI
itself, they only work if the username and password are sent in the
HTTP head
Seems like there are at least two packages for multiple assignment,
maybe one of them solves your needs, zeallot and dub.

The max argument of print.default() does not override
options(max.print), see below.
R 3.5.1 and R-devel both seem good.
