Dear all,
Sorry if this is something totally obvious but I am learning to use org-mode for my everyday work with R. I just installed the latest stable release of org-mode (v7.01g) on top of GNU Emacs 23.1.50.1 (x86_64-apple-darwin10.2.0, NS apple-appkit-1038.25). I also installed the CRAN ascii package v0.7 on top of R v2.11.1. I am currently working on a MacBook pro with Snow Leopard 10.6.4
Early on today, while reading the org-babel intro, I was able to run the following example but somehow, later tonight, it started to break and I spent the last few hours scratching my head to understand what change and why it now suddenly break. Your help will be greatly appreciated as I am discovering that org-mode in collaboration with org-babel have great potential to help us create more readable report of our daily analysis, as long as I can get through these early hurdles.
Here is the org buffer that now breaks:
* Two examples of R code that worked when I started the tutorial but suddenly started to fail...
** some R code that should generate a nice table
#+BEGIN_SRC R
library(ascii)
options(asciiType="org")
d <- as.data.frame(replicate(4,rnorm(100)))
ascii(cor(d),include.rownames=T, include.colnames=T,header=T)
#+END_SRC
** Some code straight from [[http://orgmode.org/worg/org-contrib/babel/languages/org-babel-doc-R.php][org-babel]]
#+BEGIN_SRC R
library(ascii)
options(asciiType="org")
ascii(summary(table(1:4, 1:4)))
#+END_SRC
With the following error recover from the *Org-Babel Error* buffer
Loading required package: proto
Error in as.data.frame.default(x[[i]], optional = TRUE) :
cannot coerce class 'c("ascii", "proto", "environment")' into a data.frame
Calls: write.table ... data.frame -> as.data.frame -> as.data.frame.default
Execution halted
Thanks for the helps.

Aloha Marco,
Here is the code behind the Worg page:
#+begin_src R :results output org
library(ascii)
options(asciiType="org")
ascii(summary(table(1:4, 1:4)))
#+end_src
This works here.
The key seems to be the header argument :results output
#+BEGIN_SRC R :results output
library(ascii)
options(asciiType="org")
d <- as.data.frame(replicate(4,rnorm(100)))
ascii(cor(d),include.rownames=T, include.colnames=T,header=T)
#+END_SRC
#+results:
#+begin_example
Welcome to R!

With it added to your other example, it does indeed generate a nice
table.
I think you are absolutely right about org-mode's babel capabilities
helping with your R work. I can't imagine a better environment for
working in R.
Good luck with your work.
All the best,
Tom

The code you say is "straight from ...org-babel-doc-R.php" is not quite.
Note all the header args:
#+begin_src R :results output code :session ascii
Also note that ascii() does not return an object of class "matrix" or
"data.frame". Try str(ascii( < all the rest > )).
With :results value (the default) you will get a different outcome as
you saw below.
'value' tries to be smart about what it does with .Last.value, but "ascii"
objects are a bit too tricky for it.
'output' on the other hand is pretty simple on the elisp side and
relies on R's print() to get the dispatch for the print method right.
If you want to use ':results value' you will need to form a data.frame
from ascii() yourself, rather than rely on as.data.frame to find a method
to do the conversion. Or you will need to write a method for
as.data.frame.ascii.
HTH,
Chuck

I think you need to add 'results output org' to the header.
Do not try to convert ascii objects into data.frame, ascii() just
print several classes or R objects with org markup. Not all R objects
are supported, see methods(ascii).
Some examples here:
http://orgmode.org/worg/org-contrib/babel/examples/ascii.php
The source code here:
http://repo.or.cz/w/Worg.git/blob_plain/HEAD:/org-contrib/babel/examples/ascii.org
