Oh, I just got an even stranger result, with the latest from git... #+begin_src calc :var y=[1 2 3] 3 y #+end_src #+results: : 3 hline something is most certainly wrong... Alright, I've made two changes, first, it is now possible to pass elisp vectors through to code blocks, e.g., #+begin_src emacs-lisp :var data=[1 2 3] (elt data 1) #+end_src #+results: : 2 Second, I've added a slightly hackey but seemingly necessary post-processing step to a call to calc-eval in ob-calc to remove quotes from vectors. This allows vector processing to take place---at least as far as my limited calc knowledge is concerned. For example; #+begin_src calc :var y=[1 2 3] 3 y #+end_src #+results: : [3, 6, 9] Hope this helps -- Cheers -- Eric _______________________________________________ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.
