I haven't tried it, but I guess that without the comint-scroll-to-bottom-on-output variable set,
it will be in the middle again before I can presss Ctrl-c to interrupt R.

As I mentioned, I start R under ESS with the --vanilla option, which does not load any config
files. The reason is that I run simulations locally and on a cluster and would like to keep
settings consistent without having to worry about different config files.
