Hi
I want to load some R code into org when using R with org (i.e. in
ob-R.el) which would be part of org mode. Therefore I have two
questions:
1) Where can I put the R code? My idea would be to put it in
ORGDIR/etc/R/ - would this be OK with the general philosophy of directory
structures?
2) How can I get the ORGDIR under elisp, so that I can use it to load
From ORGDIR/R/*.R ?
Thanks,
Rainer

I can't parse this too :) If that helps, please send a patch with
what you would do, and we'll discuss from the patch.

No - there is quite a bit of R code in ob-R.el which gives quite abit of
options for customization. As R users are usually more comfortable with
using R then elisp, I am moving the R code into external .R files which
are loaded and the code in these is used for variable transfer and
(planned) the wrapping when creating graphs. Fallbacks, i.e. default
code stored in ob-R.el when the file can not be loaded, id=s in the
process of being implemented. You can see how it looks in [1] where my
changes are sitting.
And I want to load this R code into R, controlled from org.
Here is the relevant code:
,----
| (defun org-babel-expand-body:R (body params &optional graphics-file)
| "Expand BODY according to PARAMS, return the expanded body."
| (mapconcat 'identity
| (append
| (when (cdr (assoc :prologue params))
| (list (cdr (assoc :prologue params))))
| (list
| " while ('org:functions' %in% search()) { detach(pos=grep('org:functions', search())) }
| attach( what = NULL, name = 'org:functions' ) ")
| (list
| (format " userdir <- '%s'
| for( f in dir(userdir, pattern='.R', full.names=TRUE) ){ try(source(f, keep.source = FALSE)) } " org-babel-R-directory-in-org))
| (list (format " .org.createEnvironment('%s')" org-babel-R-variable-environment-name ))
| (org-babel-variable-assignments:R params)
| (list body)
| (when (cdr (assoc :epilogue params))
| (list (cdr (assoc :epilogue params)))))
| "\n"))

I am using at the moment the following construct to get the directory I
want:
,----
| (defvar org-babel-R-directory-in-org
| (mapconcat 'identity
| (append (butlast (split-string (locate-library "org") "/") 2)
| '("etc" "R" ""))
| "/")
| "Original org directory from which the *.R files will be loaded.
| This value should *not* be changed and is determined by the
| installation location of org.")

Hi Rainer,
You might want to look at how ESS handles a similar situation, via the
variables ess-etc-directory and ess-lisp-directory in the ess-site.el
file.

Ok, I understand now -- then yes, you can use the etc/ directory
for R code that will be loaded. But please anticipate that this
new etc/ content needs to be added to Emacs when people install
Org -- see how ox-odt.el is dealing with the issue of adding
the data in etc/schemas and etc/styles.
HTH,

Thanks for the hint to look at ox-odt.el ant their file in etc/ - I was
thinking about the installation issue but didn't look at it in detail
yet.
