Re: [O] [babel] [bug] bug in R-specific header argument for graphics driver

[Eric Schulte]

Hi Rainer,

I see you CC'd me on this email.  I personally do not know anything
about how the graphics header argument to R code blocks works.  I would
recommend looking deeper into the behavior using the following tools

- Look at the expanded code block body using org-babel-expand-src-block
- Run the code block in a session, and then look into the session buffer
  to see what R code is being generated by Babel, then try to debug the
  R as you would normally
- look into the temporary R scripts generated during execution, which
  will live in a directory with a name like /tmp/babel-XXXXXX

If you are able to isolate a bug in Babel then I can help fix that bug
in the elisp code.

Thanks and sorry I can't be of more immediate,
