[Orgmode] [babel] Problems sourcing R code

[Weiss, Bernd]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Dear all,

I am having trouble sourcing R code from within an org-file via
org-babel, i.e. I cant' replicate the most simple examples

#+begin_src R :results value
matrix(rnorm(6), nrow=2)
#+end_src

That's the error message I get whenever I type in C-c C-c:

"executing R source code block...
Die Syntax für den Dateinamen, Verzeichnisnamen oder die
Datenträgerbezeichnung ist falsch.
No result returned by source block"


However, I am not having any problems with the shell-example

#+begin_src sh
  echo "This file takes up `du -h org-babel.org |sed 's/\([0-9k]*\)[
]*org-babel.org/\1/'`"
#+end_src

Org-R works as expected, i.e. I can source the following example without
any problems

#+RR: x <- c(rnorm(10, mean=-3, sd=1), rnorm(10, mean=3, sd=1))
#+R: title:"continuous-data" output-to-buffer:t


My setup:
- - MS-Win Vista
- - GNU Emacs 23.1.1 (i386-mingw-nt6.0.6002) of 2009-07-30 on SOFT-MJASON
- - Org-mode: Org-mode version 6.32trans (release_6.32b.127.g471c2);
- - ESS: v5.5
- - my .emacs/_emacs-File: 


Thanks in advance for your help

I can't find anything in the manual which does anything other than
search for TODO keywords, and this functionality would be pretty useful
to me - can you point to the section number?

Ah. Where can I find documentation on “the special sexp diary entries
implemented in the Emacs calendar/diary package”?

Hmm. That makes the entry unreadable as a date+time. One of the main
advantages of the usual Org date+time specifications is they're
perfectly readable even to people who know nothing about Org, Emacs, or
Lisp. Is there a way to get a readable format that still behaves as I
described?

You can also type C-h i inside emacs and navigate to "Calendar/Diary".

Well, yes. But not for every possible niche usage. Org-mode provides
human readable syntax for the majority of scenarios, but allows power
users to harness the capabilities of emacs and elisp for the rest.

Not that I know of. But since this is org-mode, you could add a note
under the diary sexp explaining what it represents.

You'd have to ask Carsten to implement a new timestamp syntax. What
would you propose as a more readable designation?

I'd agree with Russell's conclusion that if one does not use an emacs
mail client, then there is not much point to using BBDB.

But if one uses Gnus or the like, the integration BBDB offers (e.g.,
automated addition of new addresses, auto-notes, TAB completion for
addresses, etc.) is still difficult to surpass. Until someone codes some
nice integration between an org-mode address database and emacs mail
clients, switching to an org database would require one to forgo all the
nice automation that BBDB offers. (Do you really want to enter all new
email addresses manually in an org file?)

I've found BBDB to be incredibly convenient. But I use Gnus for email.
If I were using Gmail or Thunderbird or Mutt, I wouldn't use BBDB at
all.

Just a few thoughts...

Hi,

not sure if this is related -- or helpful, but here goes!

When I export the following file:

start---
* lowercase
#+begin_src python :exports results
2+2
#+end_src

* uppercase
#+BEGIN_SRC python :exports results
2+2
#+end_src
end---

the results are (copied from pdf):

start---
1   lowercase
 4

2   uppercase
2+2
end---

Writing "begin_src" in lowercase or uppercase makes a difference. I am 
not sure if this is a feature or a bug.

Oh, forgot to mention: I can't make any of the snippets you sent work. 
Everything in the source blocks is exported as verbatim text, regardless

[Orgmode] Hide tasks from the agenda until they are due

[PT]

In a previous thread
(http://thread.gmane.org/gmane.emacs.orgmode/17818) there was a
discussion about using the agenda to schedule trivial time-specific
tasks during the day which can be done at or after a certain
time. These tasks should be hidden from the agenda until their time is
due, because you cannot work on them before then, so they are just
polluting the agenda view.

Matt Lundin kindly provided a quick untested solution in that thread
which was almost complete, it needed only a bit of tweaking. Here is 
the working solution (not yes extensively tested) for those interested:


(defun my-org-agenda-skip-if-later ()
  "Skip entries that are later than the current time."
  (let ((time (and (org-entry-get nil "TIME-TODO")
   (or (org-entry-get nil "TIMESTAMP")
   (org-entry-get nil "SCHEDULED")
(when time
  (unless (time-less-p (org-time-string-to-time time) (current-time))
(or (outline-next-heading)
(point-max))

(setq org-agenda-skip-function 'my-org-agenda-skip-if-later)


The tasks to be hidden need to have a special property set (TIME-TODO)
in order to distinguish them from regular timestamps which are not hidden. 
I added this property to my remember template, so it's automatically 
set when I create such a task.

I set the skip function globally, because I use a single agenda view. You
may want to set it only for certain agenda views.

[Orgmode] [babel] :noweb

[Thomas S. Dye]

Aloha all,

The following org file demonstrates that :noweb passes silently over  
the undefined code block <>.  As my org-babel files become more  
complex, it is harder for me to catch errors like this on my own  
(e.g., when I have a typo in a reference to a srcname).


Could org-babel raise a warning or an error in this circumstance?

All the best,
Tom

It will if you use brackets to perform a regexp match. E.g.,

Keyword={example1}

(...assuming the property is "Keyword: example1 example2".)

Dear Bernd,

This is a problem relating to running R as an external shell process
under Windows. For the time-being, please use the :session header
argument to specify that evaluation is to take place in a persistent
emacs R session. Alternatively, you could use the following
configuration code to force R blocks to always use the specified session
(you can change the session name of course):

(setq org-babel-default-header-args:R '((:session . "*my-R-session*")))

Session-based evaluation is described briefly at

http://orgmode.org/worg/org-contrib/babel/org-babel.php#basic-functionality

Thanks for the report. We will investigate the issues with running R as
an external process under Windows.

Best wishes,

Dan

Bug. However I'm not sure whether it is in org-mode or org-babel. In
general in org-mode, begin_src and BEGIN_SRC are equivalent (true for
all #+XXX directives I think). However, in this case the org-exp-blocks
client (org-babel) associates 'src' with its own block exporter, but it
says nothing about 'SRC'. So the solution could either be:

(a) Bug in the org-exp-blocks client (org-babel). The client should
explicitly hook up 'SRC' to its block pre-processor.

(b) Bug in org-mode. Org-exp-blocks should call the block pre-processor
for 'src' when it finds 'SRC' (and equivalently, if a client registers
'SRC', then 'src' should trigger it.)

I'm leaning towards (b), seeing as we already have the case
insensitivity in org-mode.

This is a limitation of the current implementation of :results value
evaluation. For now, while we work out a good solution, semi-colon
separated statements on the same line (as well as multiline
continuations) should be avoided when using :results value (the
default). It does work with :results output:

#+BEGIN_SRC python :results output
import os; print os.listdir(os.getcwd())
#+END_SRC

Thanks for pointing this problem out.

That's partly my point: “second Tuesday of the month” isn't niche, it is
pretty common, I would have thought.

How about this:

<2009-10-13 Tue 14:00 +1m Tue>
Repeat each month, on the second Tuesday of the month. Calculated
because this date is the second Tuesday of the month, and the repeat
weekday is specified.

<2009-10-13 Tue 14:00 +1m>
Repeat each month, on the 13th day of the month. Calculated because
this date is the 8th of the month, and the repeat weekday is not
specified.

<2009-10-13 Tue 14:00 +1m Fri>
Invalid, since this date is not on a Friday.

Or, rather than introducing syntax that makes it easy to put invalid
syntax:

<2009-10-13 Tue 14:00 +1m dow>
Repeat each month, on the second Tuesday of the month. Calculated
because this date is the second Tuesday of the month, and “dow” is
the specified repeat type.

<2009-10-13 Tue 14:00 +1m dom>
Repeat each month, on the 13th day of the month. Calculated because
this date is the 8th of the month, and “dom” is the specified repeat
type.

<2009-10-13 Tue 14:00 +1m>
Repeat each month, on the 13th day of the month. Calculated because
this date is the 8th of the month, and “dom” is the default repeat
type.

I somewhat prefer this latter syntax, because it uses a brief keyword,
allowing for other keywords in the future if a case can be made for
other repeat types.

Same here.


I think we'd better have an easy way to use bbdb in Org-mode, just as we
have for using the calendar.

E.g.

  `C-c b n'   - complete a name (and eventually insert it as [[bbdb:]]
link)
  `C-c b m'   - complete an email address
  `C-c b e'   - complete an entire entry. A customizable format would be
great.
  `C-c b u'   - complete user defined field (two steps).


We already have

  [[bbdb:Sebastian Rose]]

  We should change that link type to DTRT. bbdb can do more, than just
  show the entry. So show a list to choose from:

 - send mail
 - give her a phone call
 - a.s.o.


Import and export

 - http://www.emacswiki.org/cgi-bin/wiki/bbdb-vcard-export.el
 - http://www.emacswiki.org/emacs/BbdbImporters

  The evolution address book and all the other mailers can import and
  export vcards.


Mangement

  Some way to search all those [[bbdb:Xxx Yyyy]] links. Maybe similar to the
  agenda interface. Would that be overkill?









I don't think bbdb's database format is odd at all. It's straight
forward.

`nil' for each entry I don't know the meaning of (this is the first time
I took a look into ~/.bbdb), the entire thing one address book entry and
on one line in ~/.bbdb:


["Firstname"
 "Lastname"
 ("AKA one" "AKA two" "")
 Company
 (["Type-of-Phone e.g. Mobile" "Number"]) ;; more entries in list possible
 (   ;; list of postal addresses
  ["Type of address 1"
("Street address 1" "Street address 2")
"City"
"State"
"Zip code"
"Country"
   ]
 )
 ("list of mail addresses" "more addresses possible")
 (
   (notes . "some notes")
   (creation-date . "2008-08-12")
   (timestamp . "2008-08-12");; last changed
   ;; eventually more entries, like the user defined once. I have ICQ
   ;; defined, and an entry would look like this:
   (ICQ . "XNN")
  )
 nil ;; list of changes at `timestamp' (I think) ???
]



Looking at .bbdb is enough to check what's going on. I don't know how it
could be easier to use.

Simple things are simple - e.g. the file format of address books. And
that's perfectly OK. Overhead and complicated tricks to handle addresses
are odd.  Handling addresses myself, if bbdb could do that, is even more
odd.


Org-mode doesn't provide desktop integration, too. So I cannot see an
advantage in using Org-mode to handle addresses.

[Orgmode] [OT] How do you keep your reference data?

[Marcelo de Moraes Serpa]

Hi list!

Information that has no potential next action associated but that still has
potential reference value and that you'd like to keep around, how and where
do you keep it ?

I usually check - if it is related to a project, I put it in this project's
wiki page (a simple .org ASCII file named after the project under ~/org/wiki
folder). If it's not, I try to find out if there's a wiki page that I could
fit it into, if not, I create a new file under the wiki folder.

I used to use tomboy, but I'm trying to move/center all my data to my org
folder. I still use Tomboy for quick notes (collection-phase) though, but
not for reference.

I then have a simple function that searches (rgrep) through the whole ~/org
folder, so that whenever I want to check if I have something about subject
x, I just rgrep my PIM folder.

;;a little elisp func to rgrep through all my org directory
(defun org-rgrep (REGEXP1) "Searches through all my org/PIM files"
(interactive "sSearch PIM for: ") (rgrep REGEXP1 "*.org" "/home/marcelo/org"
))
;;bind the previous function to windows_key + o
(global-set-key [?\s-o] 'org-rgrep)

Would you mind sharing how you do it?

Thanks,

Marcelo.

[Orgmode][babel] noweb does not work (as expected)

[Torsten Wagner]

Hi everyone,

I tried to use the noweb-syntax to tangle all the pieces of source code blocks 
together as proposed by Tom.

However, for some reasons it does not work. 
I notice there are two different syntax for noweb. One propsed on worg and the 
other in examples here in the mailing list. Which one will be correct ? or are 
both correct but with different purpose ?

I used the latest git-version and even tried the branch noweb-evaluate

What I used was a source code block at the end of my org-file like:
All other blocks are defined above.

#+srcname: makefile()
#+begin_src python :tangle simulate_ofdm :exports none
  <>
  <>
  <>
  <>
  <>
#+end_src
#+resname: makefile

However
the tangled file results only in 

#!/usr/bin/env python
# generated by org-babel-tangle
# [[file:~/test_noweb.org::*Result][makefile]]

# makefile ends here

An execution of block shows nothing on the *Shell output* buffer
It seems somehow I missunderstand which part of a block will replace a 
<>  variable. I thouht it will be replaced by the complete source block 
content during tangle. 

Any ideas ?

Thanks,

Torsten

Hi Torsten,

I've been working successfully with your makefile idea.  Here is one  
that works for me:


--

#+begin_src R :noweb :session 135cultural
   <>
   <>
   # run queries
   <>
   <>
   <>
   <>
   # reshape query results and run PCA
   <>
   <>
   <>
   # make biplots
   <>
   <>
   # segment plot
   <>
   # make tables for LaTeX
  # <>
   <>
#+end_src

-

A typical source block looks like this:

-

#+srcname: r-load-libraries
#+begin_src R
  library(RMySQL)
  library(reshape)
  library(xtable)
#+end_src

-

Note that I don't :tangle this, but use the :noweb feature, instead.   
Also, my "makefile" runs all its :noweb source blocks in a :session,  
where the environment set up by each source block can persist and be  
referenced by other source blocks.  This particular makefile has run  
successfully dozens of times, as I fix little things and add new ones.


I don't know if this is the best way to accomplish this, or if it is  
what you are trying to achieve at the moment.  But, it looks to me as  
if you might want to :noweb instead of :tangle and perhaps establish  
a :session in case your source blocks need to communicate with one  
another.


HTH,
Tom

<> inserts the body of block 'block-1'. < inserts
the *result* of evaluating block-1, and <> inserts the
result of evaluating it with the specified argument value. I've just
added documentation of this to Worg.

Can you provide the exact contents of the file you're having trouble
with? If I have


* test tangle
#+srcname: block1
#+begin_src python 
  x = 1
#+end_src

#+srcname: makefile()
#+begin_src python :tangle simulate_ofdm :exports none
  This is makefile
  <>
#+end_src


then for me org-babel-tangle produces


#!/usr/bin/env python
# generated by org-babel-tangle
# [[file:/tmp/zz.org::*test%20tangle][makefile]]
This is makefile
x = 1
# makefile ends here

Richard and Carsten,

Thanks a lot for this great work!!!  Just installed MobileOrg today and
tried it out; everything worked so well!  I really like the interface!

It might be helpful if you can list more WebDAV servers (free or not) on
the web site.

Re: [Orgmode][babel] noweb does not work (as expected)

[Torsten Wagner]

Hi Dan, 

thanks for trying helping me out
actually your example works for me after switching back to git-babel master 
branch.
However, my file does still not work and I can not see a difference between 
your 
and mine file.

I will try to minimize it now to the point where it either works or still 
fails and post it here. 
Could you please tell me which of the branches in the babel-git includes the 
best working version for noweb usage.
I got a bit confused with all this branches.
Maybe I do something wrong during the installation from git. I actually only 
run standard make; make install; 
and I set a symlink of the contrib folder into my .emacs.d from where emacs 
will find the babel files. Actually I'm wondering why the contribs are not 
copied by make into the elisp-path.

Furthermore, I noticed that babel-git uses a complete org-mode branch for the 
development of org-babel. Is this to keep org-mode freezed and to control 
merging with the main org-mode developments? 
I once read about git submodules [1]. Maybe this is interesting for org-babel.
 
Thanks again for help

Torsten

What about having some bridge between org-mode & (open)ldap-shared

Re: [Orgmode][babel] noweb does not work (as expected)

[Torsten Wagner]

Hi Tom,

If I try to use the noweb way, I always got error messages which tells me that 
org-babel can not read the result correctly

> 
> #+srcname: r-load-libraries
> #+begin_src R
>library(RMySQL)
>library(reshape)
>library(xtable)
> #+end_src


As I see you do not use any special header here which means results is set to 
value, right? However, there is no special return line to org-babel either. In 
my understanding and according to my error messages  library(xtable) would be 
evaluated as the result of this block...

However this results in error messages at least for python.

Which org-babel version due you use (which branch)?

Maybe you or someone else can bring some more light into this :results topic.
I somehow miss the option :results none to avoid any results which should be 
useful if the source code block is just a piece of a bigger arrangement. For 
literate programming and RR it might be essential to spread blocks over the 
file which will be tangled together (by tangle or a noweb block). However not 
all need provide a result but just need to run in the same session. Maybe just 
the last block of such an arrangement will come up with a result suitable for 
org-babel.
 
Actually I prefer the idea of :noweb instead of tangle, which seems to me more 
flexible and faster.

Just need to get it running

Thanks 

Torsten
