The org-babel default is to invoke R as an external shell command, and I think this is what is causing the problem. It requires that the emacs function shell-command can use the string "R" to invoke an R process, i.e. the R installation and the shell path must be such that this is the case. Seeing as you have ESS installed, how about using session-based evaluation? This means that org-babel uses an interactive R session running under the control of ESS. In general it is a better way to work with R in org-babel. It is described in the section "Session-based Evaluation" in http://orgmode.org/worg/org-contrib/babel/intro.php and also in the reference manual: http://orgmode.org/worg/org-contrib/babel/reference.php#header-argument-session basically you just set the :session header argument, e.g. #+srcname:trial #+begin_src R :session org-babel-R-session c(4,5,6,7,8,9) #+end_src Have a look here to see the different methods you can use to make this the default (without having to explicitly set the header arg each time) http://orgmode.org/worg/org-contrib/babel/reference.php#sec-3.1 Dan > > I have a look on temporary directory and I have the folllowing > file : > > R-in-functional-results4452lyl > > Inside the following source code : > > main <- function () > { > > c(4,5,6,7,8,9) > > > } > write.table(main(), file="c:/Temp/emacs/tmp/R-out-functional-results4452y8r", > sep="\t", na="nil",row.names=FALSE, col.names=FALSE, quote=FALSE) > > > The file R-out-functional-results4452y8r exists but is empty. > What I miss to make it work ? > > Regards > > > > _______________________________________________ > Emacs-orgmode mailing list > Please use `Reply All' to send replies to the list. > Emacs-orgmode@gnu.org > http://lists.gnu.org/mailman/listinfo/emacs-orgmode _______________________________________________ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.
