To answer my own question. My mistake was that "ulimit -c unlimited" applies to the current bash session only. I had used this call in a bash *shell* buffer in emacs but this was unable to affect R processes started in emacs with C-u M-x R, hence no core files. Running the buggy code from R started in a bash shell after running ulimit resulted in a core file being generated in the R working directory.
It's not the cleanest of emacs solutions, but at least it works. David ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
