[R] Help needed: plotting with no device
I have a hung session I would very much like to recover, since it has some simulation results I haven't saved (that took about 12 hours to create). Yes, I know, I should have saved while I had the chance. I tried to do a hist() in an environment without a plotting device. My R session now seems to be hung; ^C doesn't do anything. I thought it would timeout, but it has not so far. The details of this session's environment are a bit baroque. In case it matters, here they are: Running an xterm locally, used the screen program to start a shell. Ran R. Then, from a remote computer, used ssh to log in (without X forwarding enabled). Grabbed the session by doing screen -d -r. (screen lets you trade the controlling tty of a session; that's why I was using it). After detaching and reattaching the session a couple of times (still remote) I did hist(tres4$singles[[a]]) tres4$singles is a dataframe. I can still type on the terminal, but get no response. R 1.7.1 on Debian. Is there any way to get the R session back without killing it? Thanks. __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
Re: [R] Help needed: plotting with no device
Can you use save.image() to rescue your results? I would try save.image(file=salvage.RData) and see if the file appears. Otherwise I would say you're probably out of luck.

It may be possible to reconstruct the state from a core dump. I say may with not much confidence it'll be worth the effort, but it might be possible. Only problem is, there's no way I know under Linux to dump core and continue; you only get one shot at it. man 7 signal on my SuSE box gives a list of which signals cause a process to dump core. After that, you'll have to find a Local Guru to pick it apart - and R's memory structures aren't trivial. It might be easier to start again.

You may be able to send SIGUSR1 to the process, which tells it to quit and save, or SIGUSR2, which is quit and save without running .Last and .on.exit stuff. It depends on how badly it is wedged. -thomas __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
