Cedrick is correct. I was referring to the command invoked by entering the string "screen" at the shell prompt.

Is there any way you can put your commands in a script and execute them from the command line so that you see the actual memory and GC output from R in realtime? I use the following (in WinXP) to debug any faulty processes or detect if the job was actually completed successfully: (adapted for Linux, *not* winxp) R --verbose MorningStartup.r > morningsummary-log.txt That should yield some more results which hopefully should help you investigate. The pertinent stuff is output to the console. -cedrick Peng Yu wrote: > I run R in gnome-terminal.
