I'm having some trouble following the instructions in the FAQ for debugging. I can run 'R -d gdb' at the command line and it works; also, I have run gdb from emacs before. But I can't figure out how to put the two together: I've tried following the instructions in the FAQ, but I seem to be missing something. Can someone with experience tell me exactly how I should invoke gdb on R from within emacs? Thanks. -John Barnett -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help 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 !)

Hmm. I don't usually do that, but both of the following seems to be somewhat in the right direction: C-u M-x R and then give options -d gdb (requires ESS) or M-x gdb and then give R -d gdb as startup command

A third option is to start R within ESS mode (M-x R) and load whatever R libraries that you want, then start gdb (M-x gdb) giving $RHOME/bin/R.X11 as the program to debug. Use the program "ps" to find the process number of the currently running R process then use use the "attach" command in gdb to attach gdb to that process. One advantage of this method is that you have separate *R* and *gud-gdb* windows. Within the *R* window you have all the ESS facilities, such as object-name completion, that we know and love. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help 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 !)
