It shouldn't do this when you are running under ESS. One quick fix might be to install a terminfo entry for the "emacs" terminal type but I'm not sure how you do that. I had thought that when ESS started the R process it should send the -noreadline flag to it. From the R manual page The following options are present to support the use of R from other programs. In particular, the -noreadline option exists so that R can be run under emacs(1) and xemacs(1) using ESS. -noreadline Turn off the use of the readline(3) command line editing. If R is getting the -noreadline flag properly then my guess is that the call to initialize the readline library (probably in $RHOME/src/unix/system.c) is not being protected by an if statement that checks for this flag. Earlier I reported a problem in $RHOME/src/unix/system.c that some ifdef's were checking for HAVE_READLINE_HISTORY_H but that variable was not being defined by the autoconfigure script. I'm not sure if that has been corrected yet. When I was looking for those definitions I noticed the autoconfiguration on the version I compiled for Debian Linux 2.0 does not set HAVE_READLINE but that version on Debian Linux 1.3 does. This looks like another autoconfigure problem. -- Douglas Bates bates@stat.wisc.edu Statistics Department 608/262-2598 University of Wisconsin - Madison http://www.stat.wisc.edu/~bates/ -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

I don't see that the -noreadline flag is being passed to R when invoked by ESS. cd /usr/lib/xemacs/site-lisp/ESS-5.0/ grep -n noreadline *.el /dev/null # no responses. Try starting R by C-u M-x R and when it asks for "Starting Args ?" put in the -noreadline flag. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

ESS-5.0 does not yet contain the "-noreadline" flag.
ESS-5.0 came out only very shortly after R 0.60,
if "-noreadline" would have been builtin, no R version < 0.60
would have worked....
Here is the patch --- apply it if you are willing to only use
R versions >= 0.60 (with ESS):
Excuse that I didn't give this answer earlier...
