These blocks do not have their own body. Instead they use
|
|
a :srcname header argument to reference a different source
|
|
block, whose body they use. Source blocks in the library of
|
|
babel should use a standard naming scheme for the variable
|
|
containing the input data for analysis / plotting. E.g. if that
|
|
variable is always called __data__ then one of these bodyless
|
|
babel blocks will call a library of babel block using :var
|
|
__data__=<some reference>. The header args from a babel block
|
|
are appended to the header args from the target block.
|
|
|
|
This function is called by `org-babel-execute-src-block'."
