In addition to evaluation of code blocks, org-babel allows them to
|

be parameterised (i.e. have arguments). Thus source code blocks

now have the status of *functions*.

* Spreadsheet plugins for org-mode in any language
|
||||
|
||||
*NOTE*: Maybe in-addition-to/in-stead-of this example we should do a
|
||||
more traditional "spreadsheet" example with R [Eric]
|
||||
|
||||
Not only can Org-babel pass entire tables of data to source code
|
||||
blocks (see [[arguments-to-source-code-blocks]]), Org-babel can also be
|
||||
used to call source code blocks from *within* tables using the
|
||||
Org-mode's [[http://orgmode.org/manual/The-spreadsheet.html#The-spreadsheet][existing spreadsheet functionality]].
|
||||
|
||||
In fact the functional test suite for Org-babel is implemented as a
|
||||
large Org-mode table. To run the entire test suite you simple
|
||||
evaluate the table =C-u C-c C-c=, and all of the tests are run
|
||||
updating the table with pass/fail statistics.
|
||||
|
||||
Here's a sample of our test suite.

What about those source code blocks which are so useful you want to

have them available in every org-mode buffer?
