Hi
I would like to use :prologue and :epilogue to enclose the code block
in a local({}) block, i.e.
* test
#+begin_src R :prologue local({ :epilogue })
qwerty <- "test"
#+end_src
But the problem seems to be the unbalanced brackets, and everything is
passed on as the prologue, as I get the error:
Error: unexpected ':' in:
"{
local({ :"
Execution halted
Can I somehow use unbalanced brackets, or is this a missing option in
epilogue and prologue?
Cheers,
Rainer

Agreed - * test #+begin_src R :results output :prologue "local({" :epilogue "})" :session cat("Test") #+end_src #+RESULTS: no :session nothing happens using :session the execution does not complete because the :epilogue is not appended. * test 2 #+begin_src R :results output :prologue "cat(1, '###\n')" :epilogue "cat(2, '###\n')" :session cat("Test\n") #+end_src #+RESULTS: : 1 ### : Test works under :session and without but * test 2 #+begin_src R :results output :prologue "{cat(1, 2 )" :epilogue "cat(2, 3)}" :session cat("Test\n") #+end_src works only without :session as R is waiting for the "}" which is in the :epilogue but which is not added.
