* Notes
** Special editing and evaluation of source code in R blocks
Unfortunately org-mode how two different block types, both useful.
In developing RweaveOrg, a third was introduced.
Eric is leaning towards using the =#+begin_src= blocks, as that is
really what these blocks contain is source code. Austin believes
that specifying export options at the beginning of a block is
useful functionality, to be preserved if possible.
Note that upper and lower case are not relevant in block headings.
*** Source code blocks
Org has an extremely useful method of editing source code and
examples in their native modes. In the case of R code, we want to
be able to use the full functionality of ESS mode, including
interactive evaluation of code.
*** Implementations

Source code blocks look like the following and allow for the
special editing of code inside of the block through
`org-edit-special'.

Unfortunately org-mode how two different block types. I'm leaning

*** Source code blocks
look like the following allow for the special editing of code
inside of the block through `org-edit-special'.
#+begin_src R
#+end_src
*** dblocks
look like the following allow for evaluation of the code inside of
the block by calling =\C-c\C-c= on the header of the block. This
is handy, as org-mode will automatically call
dblocks are useful because org-mode will automatically call
`org-dblock-write:dblock-type' where dblock-type is the string
following the =#+BEGIN:= portion of the line.
dblocks look like the following and allow for evaluation of the
code inside of the block by calling =\C-c\C-c= on the header of
the block.
#+BEGIN: dblock-type
#+END:
*** R blocks
In developing RweaveOrg, Austin created [[file:existing_tools/RweaveOrg/org-sweave.el][org-sweave.el]]. This
allows for the kind of blocks shown in [[file:existing_tools/RweaveOrg/testing.Rorg][testing.Rorg]]. These blocks
have the advantage of accepting options to the Sweave preprocessor
following the #+BEGIN_R declaration.
