After a long absence from using ESS with R in XEmacs, I am beginning to
use ESS now in Emacs. However, I have a problem when trying to use
help() or C-c C-v in an R session.
While running R in emacs in text or gui mode and trying to get help by
any method, I get an ESS Help buffer in a new window with only the
following message:
emacsclient: file name or argument required
Try 'emacsclient --help' for more information
I can't seem to get any help page to load. I presume there is something
wrong with my setup, but I can't find information about how to correct
this problem. Can someone tell me what I need to do to set up ESS
correctly on my system?
I include relevant system info below. Let me know if I have left
something out that will help you evaluate this problem:
When I start an R session, I get the following:
> if(identical(getOption('pager'), file.path(R.home('bin'), 'pager')))
# rather take the ESS one
+ options(pager='cat')
> options(STERM='iESS', str.dendrogram.last="'", editor='emacsclient',
pager='emacsclient', help.pager='emacsclient', show.error.locations\
=TRUE)
Fedora fc27

from Fedora packages:
emacs-ess-16.10-4.fc27.noarch

In my .emacs file I have:
(require 'ess-site)
(setq ess-source-directory (lambda () (concat ess-directory "src/")))
(setq ess-dump-filename-template "%s.R")
(setq auto-mode-alist (append '(("\\.[Rr]t\\'" . R-transcript-mode))
auto-mode-alist))
