Code blocks

<sec:sectionA>

Code is enclosed within #+begin_src/#+end_src blocks.

x <- 1:10
y <- 1:10

These blocks are extracted creating a source code file (tangling) with C-c C-v t. Without header arguments the code chunk is exported and tangled as is. Use C-c’ to edit the current code block. This brings up a language major-mode edit buffer containing the body of the code block. Use C-c’ again to exit. If you need to evaluate it use C-c C-c.

Header arguments

Using the header argument :exports none the next code chunk is not included in the exported file (LaTeX or HTML) but is included in the tangled file (R code). This option is useful to add configuration code that you don’t want to show in the book.

Use :tangle no if you need to exclude a code chunk from the tangled file.

References

Use C-c C-l or [[]] to insert a link or a reference: Section sec:sectionA.

Figures

Figure fig:dummyGraphic is exported to a PDF file using the header arguments

• :results output graphics. The results header argument writes the graphics output to the file specified in the =:file= header argument. You need this specification when using lattice and ggplot2 graphics.
• =:exports both=. Both the code and results are included in the LaTeX exported file.

LaTeX attributes

The next lines insert the PDF file with includegraphics inside a float figure in the LaTeX file. Use #+CAPTION to define the caption and #+ATTR_LATEX# to define the includegraphics arguments.
