I do use R quite a bit, and I can only think of "> " (at beginning of the line) as the command prompt, along with "+ " (at beginning of the line) as a continuation prompt for multi-line commands. I don't know what "\" or "." provide (I don't think this has changed over the various R versions) . A complication might be that the user can change the command prompt (and continuation prompt) to something else they like ( see here: http://cran.r-project.org/doc/manuals/r-release/R-intro.html#Customizing-the-environment ). For the time being I've taken the "\\." out of my local version of ob-R.el (then byte compiled and loaded) and it seems to work fine. Maybe this is a question for the ESS developers who use R extensively and probably might be able to provide some more definitive guidance on this than I can? Thanks, Andreas
