Gotcha. So if it interferes with org-src-preserve-indentation, that's
good to know. I'm assuming that was the change you recently pushed per
the last note.

Sorry, what I meant is that at no point in our dialog did you seem
surprised by my outcomes. First, you simply said you couldn't
reproduce. Then you said the issue was because I was /using/ tabs (vs.
spaces). When I disagreed, you clarified that saying I was /using/
tabs had really meant I had indent-tabs-mode set to non-nil. From my
non-mastery of Org/emacs perspective, it appeared you knew what was
going on, but revealed it in layers to me.

Awesome. Tried both methods, both of which work exactly as I'd have hoped!
- Putting =(setq org-src-preserve-indentation t)= in .emacs
- No setting for the above variable, but using =-i= in the src block

Thanks so much! This has perplexed me for a really long time, but I've
never looked into it. I'm giving my first more "major" talk at a local
event (talking about R + geo-spatial data as well as Shiny interactive
web-apps), and wanted my code to look nice and pretty. Many thanks for
enabling that!!

I'll be on the lookout for somewhere on Worg where I can add the new
documentation if you haven't done so already.


Best regards,
John
