R and unix tool 'screen'
Hej Giampiero! Odd. Using Screen version 3.09.11 and R-1.8.0 on a Debian system, R does not trap C-a. I can fire up R in a screen, create a new screen with C-a c and even detach/reattach the screen session. The terminal emulator is xterm. Perhaps you are using a terminal that traps the C-a? (just a wild guess..). Mvh, /Fredrik Karlsson

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
