I did my best to provide one, other than the file, which I offered to provide if others requested that I upload it somewhere. Since you have done so, so have I: - https://docs.google.com/open?id=0BzQupOSnvw08WHdabHh5VVczRGM Let me know if that doesn't work. I put it on Google docs and sometimes have issues with the sharing settings... You will find the rest needed for a complete ECM of my setup in the original email: - minimal config I used with `emacs -Q --load=file` - org file with minimal babel R block Let me know if you can reproduce with the linked file. I'm open to suggestions on how to bisect a file, though it's a column of strings and several columns of numbers, I'm not exactly sure what to look for.
