[ESS] Read R manuals inside emacs

[Naresh Gurbuxani]

Thanks everyone for your prompt response.

My R installation does not have info files for R manuals (R-intro) etc.

In the main directory after typing
C-h i

None of the manuals are displayed.

I need to be create the info files.  After that I am good to go.

Yes, if you have the info files installed. Which I presume is the default; I
am on Linux where the distribution packages tend to have them. (I look after
the ess package for Debian/Ubuntu [but that is irrelevant as there are no
more ess releases, hint, hint, ...]).

I have quite a few:

  edd using rob:~$ ls -1 /usr/share/info/*info*gz | wc -l
  120
  edd using rob:~$

| info -f R-intro
|

C-h i       gets you the list of all manuals the within-emacs info reader
            knows / are in the standard info location (iirc you can override
            with env vars, on Linux you generally do no need to)

m R Ex<TAB> then tab-completes to 'R Extensions' and

m R Intro<TAB>   tab-completes to the 'R Introduction'

and so on. There are info-reading keyboard command shortcuts to browse. It is
actually the main way in which I read / have read / am reading these
files. (Though the quarto-built ones at https://rstudio.github.io/r-manuals/
are very nice to link to.)

Sure, why not?
