replacing any previously inserted results
|

silent -- no results are inserted into the Org-mode buffer but

the results are echoed to the minibuffer and are

process)

file ---- the results are interpreted as a file path, and are

inserted into the buffer using the Org-mode file syntax

|
drawer -- results are added directly to the Org-mode file as with
|
|
\"raw\", but are wrapped in a RESULTS drawer, allowing

|
them to later be replaced or removed automatically.
|
|
|
|
org ----- results are added inside of a \"#+BEGIN_SRC org\" block.
|
|
They are not comma-escaped when inserted, but Org syntax
|
|
here will be discarded when exporting the file.
|
|
|
|
html ---- results are added inside of a #+BEGIN_HTML block. This
|
|
is a good option if you code block will output html
|
|
formatted text.
|
|
|
|
latex --- results are added inside of a #+BEGIN_LATEX block.
|
|
This is a good option if you code block will output

latex formatted text.

code ---- the results are extracted in the syntax of the source
