Hi all,
    I am looking at the Babel R example in
http://orgmode.org/worg/org-tutorials/org-R/org-R.html

This short example show how to use code block in Org Tables.
The example first makes an org-mode table, which I can follow and reproduce
the result:

#+name: tbl-example-data()
#+begin_src R
runif(n=5, min=0, max=1)
#+end_src

#+RESULTS: tbl-example-data
|  0.118510485393927 |
|  0.742342338664457 |
|  0.438421099446714 |
| 0.0867570964619517 |
|  0.604204315226525 |

Then it defines r source code block and use TBLFM

#+name: R-mean(x)
#+begin_src R
mean(x)
#+end_src

#+RESULTS: R-mean

#+tblname: summaries
| mean   |
|--------|
| #ERROR |
#+TBLFM: @2$1='(sbe "R-mean" (x "tbl-example-data()"))

When I export to html(C-c C-e h o), the  #+TBLFM seems to be ignored and
shows  no effect. When I place my cursor in the table and recalculate the
table formula using C-u C-c C-c in the table. I got an error as shown
above.   In the *Message* buffer, I can see the following messages.
byte-code: Beginning of buffer [8 times]
Re-applying formulas to full table...
Re-applying formula to field: @2$1
Re-applying formulas to full table...(line 1)
Re-applying formula to field: @2$1
Re-applying formulas to 1 lines...done
Re-applying formulas...done [2 times]

Any steps I missed? I am using org mode 8.2.6

Also, I found this tutorial for org-R
http://orgmode.org/worg/org-tutorials/org-R/org-R.html, however, the
org-R-apply function seems no longer available in my org mode 8.2.6. Is
org-R supposed to be deprecated?

Thanks.

No, but it's moving.  Since ob-R.el is perhaps one of the most useful
Babel library out there, we need to document the changes carefully in
etc/ORG-NEWS.

Thanks Bastien. I see ob-R.el from org-mode repos has been updated. So is
the org-R from git-repos ready to use? Could you suggest  a good place to
start learning the new org-R? The source file ob-R.el?

The recent committers to ob-R.el we be more in a position to help here
but yes, reading the source is certainly a good start.

I hope we will have a clear picture of what changed in ob-R.el in 8.3,
together with updated tutorials.

Best,

I am looking at a simpler example, the pie-chart example as in this link:
http://orgmode.org/worg/org-contrib/babel/intro.html#literate-programming

This example(src code attached in the end) first generates a table by a
shell command and then run a R one-liner which uses the table.  However,
when the R code is evaluated, I got an error about the object dirs not
found.  This is what I got in the buffer running R:
-------------------------------
options(STERM='iESS', str.dendrogram.last="'", editor='emacsclient',
show.error.locations=TRUE)
>
Error in pie(dirs[, 1], labels = dirs[, 2]) (from
test-org-babe-meta-programming.org@24170fIx#1) : object 'dirs' not found
-----------------------------------------------

It looks like that the conversion is wrong.  When I run
`org-babel-expand-src-block`
on the R source code, I don't see the R object dirs is expanded to
anything. I don't understand how the conversion works, and how Babel passes
the table to R. Any explanation is appreciated. Which function/file should
I look at? Are there working examples for passing a table to R? Thanks.

AFAICT, the arguments to code blocks may not be defined and set in the
`name' line anymore: this must be done on the `begin_src' line.

So, the following should work:

  #+name: directory-pie-chart
  #+begin_src R :var dirs=directories :session R-pie-example :file ~/tmp/dirs.png
    pie(dirs[,1], labels = dirs[,2])
  #+end_src

Best regards,
  Seb

Yes, it works. Thanks, Sebastien.

or, on a separate #+header: line.

Indeed.  I tend to forget to use that; thanks for mentioning it!
