[OS X Emacs] How to overwrite global line-wrapping setting for a specific mode?

[Marius Hofert]

Dear David,

I searched the archives on http://search.gmane.org/ for "visual line", for "ess-mode-hook", and for "R-mode-hook" but haven't found anything recently on that topic. Do you remember the context?

Apart from that, searching for "ess-mode-hook" brought:
(add-hook 'ess-mode-hook 'turn-on-auto-fill)
(add-hook 'inferior-ess-mode-hook 'turn-on-auto-fill)
But I couldn't figure out how to replace the "auto-fill" mode by "truncate". I tried (without success):
(add-hook 'ess-mode-hook 'truncate-lines)
(add-hook 'inferior-ess-mode-hook 'truncate-lines)
and:
(add-hook 'ess-mode-hook
          #'(lambda () (setq truncate-lines 1)))

Cheers,

Marius

How can I "locally" overwrite this by "truncate" in R mode? So whenever an .R file is open, it should wrap lines with the option "truncate" rather than "word wrap".
