[ESS] help("foo") opens web browser but ?foo doesn't

The reason I prefer html help is mainly practically. When working with Emacs, I usually have one Emacs frame open with two windows on my main screen, Source plus R. Then, I would like to open all help pages in a separate window on a different screen.
This is no problem when using html help, as they simply open in a new tab in the browser.
In contrast when using emacs help, even when setting up another frame with the help file, the next help file will usually be opened in the frame that was the last one active and not in the designated one on the extra screen. So either the source or the R process is hidden and I need to reset the old behavior using some C-x o C-x <left/right> combinations.
Additionally, I like to klick on the "See also" links.
But as I said in the discussion a little further done in this thread, I figured the issue is caused by the following line which is always called at the beginning of any R process, seemingly by ESS:
If you could tell me which variable I have to alter to change this to help_type = "html" that would solve my problem.
