[ESS] ess-toggle-underscore not working in init.el

[Frede Aakmann Tøgersen]

Hi

I am using the Goulet Emacs installation.

If I put (ess-toggle-underscore nil) in my .emacs (which is in my home directory) file I get the same error as Gregory. However if I put it in the file /path/to/GNU Emacs 24.3/site-lisp/default.el after the (require 'ess-site) it works.

I guess .emacs is 'sourced' before default.el when starting Emacs in the Goulet installation. In that case ess-toggle-underscore has not been defined yet.

I am not sure how this could be handled graceful. I think that there is a recommended sequence of opening system-wide, personal, and other init files for Emacs. Don't know if Vincent Goulet's installation adhere to that.  

Yours sincerely / Med venlig hilsen
