Yes. I guess I didn't explicitly say, but I mentioned that I had
triggered something goofy by accident in my earlier hunt for edebug.
I'll walkthrough right now:
- Got to ob-R.el in emacs
- C-s to find org-babel-R-evaluate-external-process
- C-u C-M-x
- Minibuffer: "Edebug: org-babel-R-evaluate-external-process"
- Visit file test.org
- C-c C-c on the src block
- Well... of course it works now. Not sure what I was doing wrong before.
I pressed space continually until failure, then again to verify the
failing line. It's this one (line 313):
,---
| (output (org-babel-eval org-babel-R-command body))))
`---
When I run this line:
,---
| (org-babel-eval org-babel-R-command
`---
I get this in the minibuffer:
,---
| Result: "C:/Progra~1/R/R-2.15.0/bin/R"
`---
Should I be able to run this from the Windows cmd prompt successfully?
I think this is my problem. Even using tab completion to ensure the
path is correct, I get the same error message "The system cannot find
the path specified" when I run this from cmd!
I guess I honed in on my problem. I can run R from my Start Menu shortcut fine.
Update: I'm on 64bit and just now realized there's another set of R
cmds in ../R-2.15.0/bin/x64/. This is what I needed.
Now my problem is that using R along doesn't produce any output. With
the above modification, I get:
,---
| Fatal error: you must specify '--save', '--no-save' or '--vanilla'
`---
I'm quite close! If I add --no-save, I get exported results but they
include all of the R preamble text from when it starts. Here's my
block for reference:
#+begin_src R :results output org :exports results
x <- c(1:10)
summary(x)
#+end_src
Thanks,
John
