html help

[Fox, Gordon]

Hmm, on my installation evaluating this code locks Xemacs up until I kill
the R process.

Cheers,

R help in an emacs buffer is neither feature nor bug.

It is a default value that

"Fox, Gordon" <gfox at chuma1.cas.usf.edu>

doesn't want.



Therefore change it with ess-htmlhelp.el:

------------------------------

;; To run R from the *R* buffer and also use html help.

;; rmh 2003 Dec 17

;;

;; Start R with M-x R, then from the *R* buffer, either

;; a. load this file

;; b. eval the next two lines with M-:

(setq inferior-ess-help-command   "help(\"%s\", htmlhelp=TRUE)\n")

(setq ess-help-kill-bogus-buffers t)

------------------------------



At the moment, this file must be loaded each time after the *R* buffer

is started.  It can't be run from either the .emacs or site-start.el file.



A long-term solution to make this a decision that can be made once in

.emacs requires that someone in ESS-core make the

inferior-ess-help-command line in essd-r.el depend on a variable.

Currently the value of this emacs variable is hard-wired as a local

variable inside the R-customize-alist.



Having shown how to get htmlhelp from within ESS, I don't see the need for
it.

The other issue mentioned by Jonathan Baron <baron at psych.upenn.edu>,

links within emacs from one *help[R](something)* buffer to another,

can be easily be accomplished within the ESS emacs help buffers.

>From within a *help[R](something)* buffer,

highlight a word, then

    C-c C-v C-y <ENTER>

The help information of the highlighted word will appear in its own

emacs buffer.
