R and unix tool 'screen'

Sorry for the wrong terminology. I tried it again and it works now (even with readline, on RH9.0). The only way I can explain the problem I got yesterday is that the computer reacted very slowly (possibly for high load). Strangely enough, I had tried it on four different computers with the same result... Thank you for your help. Giampiero
screen R ctrl-a d [detached] screen -r works for me apart from not having the usual meaning of crtl-a. I don't think R is doing anything special, but some versions of readline could conceivably be. I used RH8.0 Linux for this test. I would suggest trying R --no-readline in case your version of readline is setting the terminal in a way that conflicts with your version of `screen'.

I have problems running R with screen. For those who don't know, screen is a unix tool that is quite handy if you want to leave a process (that outputs to tty) running when you logout, and then recover the session later on. It works like this: 1) run 'screen': you get a normal prompt as if you were in a normal shell. 2) run whatever command you like 3) press 'C-a d' to detach the session. Now you can logoff if you like 4) when you want to recover the session type 'screen -r' The problem is that R seems to catch the 'C-a' signal, and nothing happens. Since there is no way to detach the screen, there is no use to it either. Is there a way around this problem? Giampiero
