You can file it as a wishlist item in the bug trackign system. Without a compelling case or a complete and well tested patch or both I doubt it will rise to the top of anyone's priority list.

Thanks - I'll find another way to send messages to the main thread for printing. -Winston On Tue, Nov 21, 2017 at 12:42 PM, <luke-tierney at uiowa.edu> wrote: > On Tue, 21 Nov 2017, Winston Chang wrote: > >> Is it safe to call Rprintf and REprintf from a background thread?

Dear R-devel community, There appears to be an inconsistency in R C API about the exceptions that can be raised from C code. Mapping of R C funs to corresponding R functions is as follows. error -> stop warning -> warning REprintf -> message Rprintf -> cat Rprint/cat is of course not an exception, I listed it just for completeness. The inconsistency I would like to report is

Is it safe to call Rprintf and REprintf from a background thread? I'm working on a package that makes calls to fprintf(stderr, ...) on a background thread when errors happen, but when I run R CMD check, it says: Compiled code should not call entry points which might terminate R nor write to stdout/stderr instead of to the console, nor the system RNG. Is it safe to replace these calls

Thank you Luke for prompt reply. Is it possible then to request a new function to R C API "message" that would equivalent to R "message" function? Similarly as we now have C "warning" and C "error" functions. Best, Jan On Sun, Sep 15, 2019 at 5:25 PM Tierney, Luke <luke-tierney at uiowa.edu> wrote: > > On Sun, 15 Sep 2019, Jan Gorecki wrote:

Hi, I'm trying to get a toy program making use of nmmin to run successfully. I've gotten to the point of compiling. However, when I attempt to run my executable, I guess a bus error.

Hello ... With a new checkout of R-devel, I'm getting the following error on startup: Type 'demo()' for some demos, 'help()' for on-line help, or 'help.start()' for a HTML browser interface to help.

Hi. I'm new to Dovecot and about to start using it in production. In the config file, I set the option, auth_debug_passwords, to yes. I do not see any failed passwords logged, however. It did cause more verbose authentication logging, but failed passwords are still hidden. I have also set these options to yes, because I thought they might be required for auth_debug_passwords to work:

Hello ... With a new checkout of R-devel (last update was 2003-09-11) we are having a problem (it seems to be happening to all of us here on a few different machines) where during install/check/etc when the 'save image' happens (in packages using 'save image'): ** save image Error: couldn't find function "setClass" Execution halted This is for all packages that

Hello ... Using Win2K (and reportedly WinXP), when the length of the 'url' string >= 280 characters, a segmentation fault occurs. This doesn't seem to be affecting unix machines. Thanks -J

Hello ... I see that on Windows one can specify a filename as the "pkgs" argument and then set CRAN=NULL when calling install.packages() for a local file. Is there a way to do this on unix? It doesn't appear to be possible, but perhaps I am missing something here. Also, if indeed there is no method to do this on unix, is there a reason behind it or has it just never been

I initially thought this only was the case for me on R-devel, but also just tested it on the current R-patched and R-2.1.1 (so perhaps this more belongs on R-help, but ...). I'm having an odd error with the makefiles in src/library/XXX while building R. When it tries to create the 'po' directory, the Makefile specifies: @if test -d $(srcdir)/inst/po; then \ $(MKINSTALLDIRS)

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 headers. In fact specifying the username and password in the URI has been

Hello ... I found this due to a situation where installed.packages() was given a lib.loc argument that turned out to not have any R packages installed.
