Does anyone know how to interrupt R in RedHat? Neither control-c nor Esc is
working. What I don't want to do is close the window or kill the entire R
process.
Thanks,
David

ESC (at the R command prompt) will probably be seen by 'readline' as the lead-in to an escape sequence, with possibly unpredictable results. For example,> for(i in (1:10^5)){rnorm(10)}takes about 20 seconds on my old laptop. However, if I start it again, and press Ctrl-C after a couple os seconds, then it stops almost immediately. Red Hat 9.1, R version 1.8.0 But I think R may need to unwind things that it has set up before returning to the prompt when you press Ctrl-C, so if what you were doing has made a lot of heavy stuff, then it might take a while before you get the prompt back. If Ctrl-C really won't work at all, then you may have an stty problem. In a normal xterm window (shell prompt) enter stty -a which should return a lot of stuff beginning like:> stty -aspeed 38400 baud; rows 56; columns 80; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; ... ... and you need to see the "intr = ^C". If not, then you don't have Ctrl-C set as interrupt. In which case, consult "man stty"!

Patrick, control-c seems to interrupt loops, but not the display of enormous objects, as when I typed the name of a several-hundred megabyte list. Is there a way to interrupt that? control-D does not interrupt R, but kills the entire R process.

Perhaps you are in some C code that doesn't pay attention to the interrupt. I have SuSe and control-C works on all of the versions of R that I've tried.
