I actually have the same issue since the last few days. One thing I found is that the buffer local variable "left-margin-width" (C-h v left-margin-width) has been automatically changed to 2 in R buffers, while the global is 0.
I did a search in the ESS source code and I think there hasn't been any change in that. So, it remains a mystery to me. ______________________________________________ ESS-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/ess-help
