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

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.
