Hello all,
I believe this is my first post on this list, and I'm very new to org-babel, so
forgive me if I am posting nonsense. However, I'm really enthused about the
possibilities org-babel presents. Unfortunately, I can't seem to get graphics
to insert themselves properly on export. I've included an example that
reproduces my problem below. For what it's worth, I am using Windows 7 with a
freshly downloaded issue of Vincent Goulet's package. Session info:
Emacs version: GNU Emacs 23.4.1 (i386-mingw-nt6.1.7601) of 2012-02-04 on MARVIN
Org mode version 7.8.03
ESS version 5.14
R version 2.14.1
Many thanks for any thoughts or requests for more info.
Matt
org example
----------------------------
#+TITLE: An attempt to make org-mode work with R
In this example, I want to fit a regression and plot it. I'm
following the examples at the [[http://orgmode.org/worg/org-
contrib/babel/languages/ob-doc-R.html][org manual]] and Erik Iverson's
[[https://github.com/erikriverson/org-mode-R-tutorial][tutorial]].
* A stand-alone code block
First, create some data, perform a regression, and plot it. This
works great.
#+begin_src R :results graphics :file regress.png :exports both
x <- runif(n = 100, min = 0, max = 20)
y <- 5*x^2 + 0.3*x + 3 + rnorm(100, sd = 200)
f <- lm(y ~ x)
plot(x, y, bty = 'n')
abline(f, lty = 'dashed')
#+end_src
Success.
* In code blocks using ":session"
Now do the same thing, but across an unnamed session
#+begin_src R :session :exports code :results silent
x <- runif(n = 100, min = 0, max = 20)
y <- 5*x^2 + 0.3*x + 3 + rnorm(100, sd = 200)
#+end_src
Now, I would like to display the results of the regression as R output.
#+begin_src R :session :results output :exports both
f <- lm(y ~ x)
summary(f)
#+end_src
Again, success! This is really going to come in handy.
#+begin_src R :session :results graphics :file regress_session.png :exports both
plot(x, y, bty = 'n')
abline(f, lty = 'dashed')
#+end_src
This code block doesn't work. No error, but no file is created.
Also, if I press C-c C-c in the code block, in the org file I get
#+begin_example
#+results:
[[file:regress_session.png]]
#+end_example
But no file is actually created. What could be going wrong?
