[O] Bug: R code block fails on one-dimensional variable [8.2.6 (8.2.6-dist @ /Users/dmirylenka/src/org-8.2.6/lisp/)]

2014-05-20 Thread Daniil Mirylenka

I am execute the following code block,
(in an empty scratch buffer, by running 'M-x org-babel-execute-src-block'):

#+BEGIN_SRC R :var x='(1 2 3)
  x
#+END_SRC

What I expect is:

#+RESULTS:
| 1 | 2 | 3 |

Instead, I get no output, and the following error message:

Wrong number of arguments: max, 0

The problem seems to be with one-dimensional variables, like x='(1 2 3):
when I change the variable to either x=2 or x='((1 2 3)), the code works 
as expected.


Here is the output from the debugger:

Debugger entered--Lisp error: (wrong-number-of-arguments max 0)

  command-execute(org-babel-execute-src-block record)
  execute-extended-command(nil org-babel-execute-src-block)
  call-interactively(execute-extended-command nil nil)


Not sure if it helps, but for me the problem goes away when I change the 
following lines in ob-R.el:


What is there currently:

(let ((max (apply #'max (mapcar #'length (org-remove-if-not
#'sequencep value
   (min (apply #'min (mapcar #'length (org-remove-if-not
#'sequencep value

What I change it to:

(let* ((lengths (mapcar #'length (org-remove-if-not #'sequencep value)))
 (max (if lengths (apply #'max lengths) 0))
 (min (if lengths (apply #'min lengths) 0))

Bellow you can find my setup.

Best regards,
Daniil
