When running R from the terminal on Linux (Ubuntu 16.04), it core dumps whenever / wherever I press Ctrl-4 or Ctrl-\. You get thrown back to the terminal with "Quit (core dump)" being the only message. Grepping the R source code, it doesn't look like that message is generated by R itself. Over on Twitter, it has been confirmed to also happen on macOS. $ R -d valgrind --vanilla

Hello, I have compiled 0.62.4 under Linux and it runs fine (a gcc/g77 combination). When I try the same thing under AIX (4.1.5) or under dec's OSF (both also gcc/g77) I get problems. Under AIX, system.c complains: system.c: In function `waitForActivity': system.c:150: `fd_set' undeclared (first use in this function) system.c:150: (Each undeclared identifier is reported only once

So do a number of other interactive programs when working in a terminal (e.g. python) since it looks like your terminal is configured for those two actions to send the SIGQUIT signal. Whether R should ignore that signal, under some circumstances at least, is another question.

Thanks for these explanations - it all makes sense, that is, the default behavior for a process that does not capture SIGQUIT is to quit and perform a core dump (https://en.wikipedia.org/wiki/Unix_signal#SIGQUIT). Then the remaining question, as Luke says, is: should R handle this signal? For instance, in interactive mode, SIGQUIT could maybe bring up: Possible actions: 1: abort (with core

I tried to submit this in R, but not sure if it worked. When running R as sudo, using ctrl-c dumps me to the command line. Hitting exit to exit the terminal window results in R taking 100% of resources. I am using R-2.1.0 on Fedora Core 3. Thanks. Manuel

Dear list, I am trying to embed R into a C++ program. After some tinkering, reading the documentation and browsing the source code I have this more or less working. A very very condensed and very simplified version of the code is included below. The program can create plots. However, after the plot is initially drawn it is no longer updated. When scaling or updating the plot the window becomes

Heiner Schwarte has helped me with the AIX problem that I and Janusz Kawczak recently reported here. Heiner had found out earlier that there was a problem with the 'finite' c-library function [Heiner's test code see below] when gcc (and older versions of xlc) is used. He also found that instead, AIX defines a FINITE(.) macro itself in fp.h and that this would work in any case.

Dear R-devel - I have investigated the report I made at https://stat.ethz.ch/pipermail/r-devel/2008-May/049683.html some more, and believe I have enough information to warrant an update. My sessionInfo() immediately after starting R is at the bottom of this message. I decided to first concentrate on finding out why I sometimes receive a segfault while closing a graphics window while the

select() has a maximum value for the FDs it can monitor, and since the libguestfs library can be used in other applications, this limit may be hit by users in case lots of FDs are opened. As solution, switch to poll(): it has a slightly better interface to check what changed and for which FD, and it does not have a limit in the value of the FDs monitored. poll() is supported on the platforms we

Hi everybody, I've had some time and so I added a slideshow creator with the Ken-Burns-Effect to the Ogg Video Tools. Feel free to visit the following page: http://www.server.streamnik.de:88/test.html It's best viewed with the Mozilla Firefox 3.1 Beta 2, but a Cortado Player is also available for the other browsers. The code is actually not publically available, as I would like to add

Hi, I'm just starting out with R and came across R_inferno.pdf by Patrick Burns just yesterday - I recommend it! His description of how 'growing' objects (e.g. obj <- c(obj, additionalValue) eats up memory prompted me to rewrite a function (which made such calls ~210 times) so that it used indexing into a dimensioned object instead (i.e. obj[i, ] <- additionalValue). This

Hi! I'm new to R, but have worked with Splus before. I installed several packages in R (R-1.9.1) without problems, but when I try to install rgl (rgl_0.64-13.tar.gz). I get the following, and the package does not install. Any help would be greatly appreciated. I'm running R in redhat 9. Thanks, Enrique ------- [my pc]# R CMD INSTALL rgl_0.64-13.tar.gz * Installing *source* package

It is indeed the following problem. I used the RPM installation as of July 20, 2004 and had the same problem installing rgl. After fixing the following line in the Makeconf file ("-share" is missing), the installation of rgl went successfully. >This is a little strange.

While playing around with panther I discovered (with surprise) that tcltk seems to work (even if not smoothly) with RAqua without first calling tkStartGUI. I switched back to 10.2.6 and it works as well. I think this is due to the "last minute" fix in RAqua now using idle timers because of too much cpu usage. Some "mouse" trick is needed though. If you want to test it you
