R source code, break long lines

R source code, break long lines

dear all,

I'm extensively using org-mode in combination with R source code blocks.
The only thing I miss is the possibility to break long lines of R code in
the exported pdf.
Is there a way to tell org, or the latex exporter, to have automatic line
breaks for long lines?

thanks in advance!

cheers, jo

I think these are treated as verbatim... so what's in your buffer is
what you'll get in PDF. You might consider editing the block with C-c
' (Ctrl + C, then single quote). From there, when you hit a reasonable
point (<=80 characters), press return and Org will auto-indent things
pretty nicely, at least in my experience with R.

If you get odd results, perhaps check this thread, as I was having
issues with Org exporting the code blocks exactly as I'd typed them:
- https://www.mail-archive.com/emacs-orgmode@gnu.org/msg81100.html

Tl;dr is that you should check the variables
org-src-preserve-indentation, and possibly the variable
indent-tabs-mode.


Best regards,
John

"automatic" way to do that.

thanks!
