Re: [ESS] run R code upon starting each ESS session
Thanks a lot Tyler, The hook is exactly what I was looking for. I checked the documentation but I guess I should search better next time. In case somebody else is interested, I am sending the code directly from within emacs, init file so, no need for extra R scripts. It is a wonderful way to set up R sessions for me. It looks something like this: (defvar my-r-profile "message(\"Welcome from Emacs\")") (defun my-r-ess-init () "Sends variable `tt-r-profile' to an ESS process" (let ((proc (ess-get-process))) (ess-send-string proc tt-r-profile))) (add-hook 'ess-r-post-run-hook 'my-r-ess-init) In this way, whatever you place in variable is executed upon startup of the inferior R process. Cheers!

Cool question. My immediate thought (weighted by the fact that I cannot write
elisp code ;-) ) was to test for that in the _the standard R startup files_.
A quick check of what `Sys.getenv()` returns inside Emacs reveals the
`INSIDE_EMACS` env var so now I just added
if (interactive() && nzchar(Sys.getenv("INSIDE_EMACS"))) {
cat("Hello Emacs user.\n")
}
to the bottom of .Rprofile and indeed:
[... other stuff including the fortunes::fortune call output ...]
Hello Emacs user.

but not when I start R on the terminal. That could be start for you.

[ESS] run R code upon starting each ESS session
Is there a way to run R code upon starting each ESS session? Something like Rprofile but I'd like to make it more dependent to emacs. What I want is to have a few options settings in my R sessions by default. Since I use it in different computers but my Emacs configuration is shared among all of them, I would prefer to keep this also within my emacs config. It can be either calling an R script, specifying the path to Rprofile directly to ESS or passing a string of R code to run at startup.
