R help - Jan 2003 - Ideas needed on automation of R

I need some guidance on what is the best way to automate R  I am aware of
Rterm.

First question:  Is it true that R is not currently OLE accessible under
Windows 2000?
Second question: Is there an R command that echoes all R Console results to
a run log system file?

My first attempt to write a run log file is the example from the R Data
Inport/Export documentation.

> example(lm, prompt.echo = ">")
> sink()
> close(zz)
 I can't find the file "ex.lm.out" anywhere on my system's
drive.  But the
file exists in R as confirmed by the next command:
> cat(ex.lm.out, sep="\n")
Rex

Not sure about your first question.

Regarding your second question, maybe you should just sink to a file:

sink("ex.lm.out")
example(lm)
sink()

True.  No one has announced an intention to contribute such functionality,
either.

No.  Why do you want to use the `R console' (presumably RGui) to do that?
Rterms is provided.

         ^ is an error

No, ex.lm.out is an R object: please do read the help for textConnection().

You can sink directly to a file.

Rex,

Maybe RPy (Python interface to R) could be of help in automating R? Logging
is then made very flexible using Python.

- http://rpy.sourceforge.net/
- http://gestalt-system.sourceforge.net/rpy_demo.html

If you combine it with py2exe you could possibly create an
windows-executable file that controls R. Then you can also use Win2K's
(scheduled) service functionality for running the application. (This is
untried though, but assumed to work).

- http://starship.python.net/crew/theller/py2exe/

Hope this helps.

Best regards,
Amund Tveit

You will find a (D)Com server for R at
http://cran.r-project.org/contrib/extra/dcom. Otherwise, there will be a
sligthly more complex (asynchronous communication, time out management,...)
OLE server in SciViews, http://www.sciviews.org. It is not distributed yet,
but I plan to release it before mid-March or so.
