I didn't mean to imply that it does. I'm just new to signals and things that should be obvious aren't. Basically kill(2) seems to be the right thing to use, but I wasn't sure what the PID needs to be. Turns out sending SIGINT to my GUI from a shell interrupts R, so raise(SIGINT) should be enough. -Deepayan ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
