* [babel] configuring LaTeX exports verbatim environment for exported code and results @ 2010-08-31 13:08 Douglas Bates 2010-08-31 13:28 ` Douglas Bates 0 siblings, 1 reply; 3+ messages in thread From: Douglas Bates @ 2010-08-31 13:08 UTC (permalink / raw) To: emacs-orgmode I have been unable to find in the documentation whether the verbatim environment created by LaTeX exports of source code blocks can be configured. Exporting to LaTeX a section like --8<---------------cut here---------------start------------->8--- #+LaTeX_CLASS: beamer #+LaTeX_CLASS_OPTIONS: [presentation] #+BEAMER_FRAME_LEVEL: 1 #+BABEL: :session :exports both :results output :tangle yes * Fitting a simple linear regression #+begin_src R :exports results options(show.signif.stars=FALSE) #+end_src #+begin_src R summary(fm1 <- lm(optden ~ carb, Formaldehyde)) #+end_src A final line. --8<---------------cut here---------------end--------------->8--- produces the LaTeX section --8<---------------cut here---------------start------------->8--- \begin{frame}[fragile] \frametitle{Fitting a simple linear regression} \label{sec-1} \begin{verbatim} summary(fm1 <- lm(optden ~ carb, Formaldehyde)) \end{verbatim} \begin{verbatim} Call: lm(formula = optden ~ carb, data = Formaldehyde) Residuals: 1 2 3 4 5 6 -0.006714 0.001029 0.002771 0.007143 0.007514 -0.011743 Coefficients: Estimate Std.

If I could, for example, configure the names of the exported environment for the source code and for the results separately, I could use LaTeX's fancyvrb.sty to adjust font sizes, colors, boxes, etc. Also, the blank lines before and after the verbatim environment are problematic. In plain text it makes sense to delimit code chunks with blank lines but in LaTeX a blank line starts a new paragraph and you don't always want that. As this is my first posting please let me know if I have inadvertently violated conventions of the list. Also, the exports append blank lines ^ permalink raw reply [flat|nested] 3+ messages in thread
