Hi,
Is there any way that a package can listen for when R quits? The Qt stuff is
hooking into platform-specific event loops and when those die unexpectedly
(from the perspective of Qt), it aborts, causing an annoying error dialog.
If we could catch when R is killed, we could cleanup, like we do
Take a look at reg.finalizer. You'd have to create an object
internally that would persist until R exits - and a related function
to handle cleanup of course.

Thanks for the suggestion, but I don't think that R finalizes all of its
objects when it quits. At least a simple test suggests that on Linux.

See onSessionExit() in the R.utils package, e.g.
onSessionExit(function(...) {
cat(Bye bye world!\n);
})
quit();
Please pay attention to the Details section of help(onSessionExit);
there are ways that R can exit that will not be detected/handled.

Did you use onexit=TRUE? On Windows that appears to work...
