I believe that your sessionInfo() results leave out the most important
detail, which is that you're running R from Emacs/ESS. Is that right?
I get this same, occasionally annoying, behavior when using ESS 13.03 and
Emacs 23.3.1, but not from Rgui, Rterm, etc.
Haven't brought it up there, but this would obviously be a good topic for
ESS-help.
Cheers,
Josh
