Re: BUG babel :colnames

[Andreas Leha <andreas.leha@med.uni-goettingen.de>]

Hi Eric,

thanks for looking into this.  And thanks for the confirmation already!

Good to know, that it is specific to R -- I had not checked.  Of course,
I do not want to use R to do mere subsetting, but rather some more
complex processing, which I do not want to do in shell (or elisp,....)

I have some more data on this bug if this is helpful:

(1)
On normal code blocks it depends on the order of the arguments.  It
seems to work for the last argument:

--8<---------------cut here---------------start------------->8---
#+name: testtable2
| a | b |
|---+---|
| 1 | 3 |
| 3 | 3 |
| 4 | 1 |
| 4 | 2 |

#+header: :var testtable=testtable2
#+header: :var dummy=20
#+begin_src R :colnames yes
  testtable[2:3,]
#+end_src

#+results:
| X1 | X3 |
|----+----|
|  4 |  1 |
|  4 |  2 |


#+header: :var dummy=20
#+header: :var testtable=testtable2
#+begin_src R :colnames yes
  testtable[2:3,]
#+end_src

#+results:
| a | b |
|---+---|
| 3 | 3 |
| 4 | 1 |
--8<---------------cut here---------------end--------------->8---

(2)
It is also buggy in call lines:

--8<---------------cut here---------------start------------->8---
#+name: testtable2
| a | b |
|---+---|
| 1 | 3 |
| 3 | 3 |
| 4 | 1 |
| 4 | 2 |


#+name: process_testtable
#+header: :var dummy=20
#+header: :var testtable=testtable2
#+begin_src R :colnames yes
  testtable[2:3,]
#+end_src

#+results: process_testtable
| a | b |
|---+---|
| 3 | 3 |
| 4 | 1 |

#+call: process_testtable() :colnames yes

#+results:
| a | b |
|---+---|
| 3 | 3 |
| 4 | 1 |

#+call: process_testtable(dummy=24) :colnames yes

#+results:
| a | b |
|---+---|
| 4 | 1 |
| 4 | 2 |

#+call: process_testtable(dummy=24, testtable=testtable2) :colnames yes

#+results:
| X1 | X3 |
|----+----|
|  4 |  1 |
|  4 |  2 |

#+call: process_testtable(testtable=testtable2) :colnames yes

#+results:
| X1 | X3 |
|----+----|
|  4 |  1 |
|  4 |  2 |
--8<---------------cut here---------------end--------------->8---


Regards,
Andreas
