-** TODO re-implement helper functions from org-R
-*** Initial statement [Eric]
-    Much of the power of org-R seems to be in it's helper functions for
-    the quick graphing of tables.  Should we try to re-implement these
-    functions on top of org-babel?
-
-    I'm thinking this may be useful both to add features to org-babel-R and
-    also to potentially suggest extensions of the framework.  For example
-    one that comes to mind is the ability to treat a source-code block
-    like a function which accepts arguments and returns results. Actually
-    this can be it's own TODO (see [[* source blocks as functions][source blocks as functions]]).
-*** Objectives [Dan]
-    - We want to provide convenient off-the-shelf actions
-      (e.g. plotting data) that make use of our new code evaluation
-      environment but do not require any actual coding.
-*** Initial Design proposal [Dan]
-    - *Input data* will be specified using the same mechanism as :var
-      references, thus the input data may come from a table, or
-      another source block, and it is initially available as an elisp
-      data structure.
-    - We introduce a new #+ line, e.g.  #+BABELDO. C-c C-c on that
-      line will apply an *action* to the referenced data.
-    - *Actions correspond to source blocks*: our library of available
-      actions will be a library of org-babel source blocks. Thus the
-      code for executing an action, and the code for dealing with the
-      output of the action will be the same code as for executing
-      source blocks in general
-    - Optionally, the user can have the relevant source block inserted
-      into the org buffer after the (say) #+BABELDO line. This will
-      allow the user to fine tune the action by modifying the code
-      (especially useful for plots).
-    - So maybe a #+BABELDO line will have header args
-      - :data (a reference to a table or source code block)
-      - :action (or should that be :srcname?) which will be something
-        like :action pie-chart, referring to a source block which will
-        be executed with the :data referent passed in using a :var arg.
-      - :showcode or something controlling whether to show the code
-      
-*** Modification to design
-    I'm implementing this, at least initially, as a new interpreter
-    named 'babel', which has an empty body. 'babel' blocks take
-    a :srcname header arg, and look for the source-code block with
-    that name. They then execute the referenced block, after first
-    appending their own header args on to the target block's header
-    args.
-
-    If the target block is in the library of babel (a.o.t. e.g. the
-    current buffer), then the code in the block will refer to the
-    input data with a name dictated by convention (e.g. __data__
-    (something which is syntactically legal in all languages...). Thus
-    the babel block will use a :var __data__ = whatever header arg to
-    reference the data to be plotted.
