Subject: 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,
