R help - Jul 2010 - Problem with invoking R from the command line (Windows Vista)

Dear all

I am running in a problem when trying to run R from Windows command line.
I am runnning Windows Vista, R-2.10.1. 

I have a script I would like to run remotely from another program. As it did
not work, I thought I would test the script from the Windows command line
which highlighted a problem. 
When I open the command line and type R at the prompt (or any other variant
(R CMD BATCH, Rgui.exe or Rterm.exe), I get the error message: 
"'Rscript' is not recognized as an internal or external command,
operable program or batch file."

if I move to the R directory (cd usr\R\R-2.10.1\bin), and try running the
script ( R < "myscript.R" --vanilla) 
 it works fine. 
I thought the problem may come from the environment variables (tried
specifying explicit location of R.exe), but this did not solve the problem.
I also re-install R but that did not help either.

I cannot think of anything else. 
I have read the R installation and rwfaq notes, and look through the posts
but I cannot find any suggestion on how to fix the bug.

If anyone can suggest anything, that will be much appreciated.

Many thanks

Camille

PS: I am also running R on another machine (Windows XP) and I don't have a
similar problem!

This is a sign that your PATH environment variable doesn't include the 
directory RHOME\bin.

You don't say exactly what you tried, but if you tried changing your 
PATH, you should try again, and verify that the change is in place in 
the session where you're trying to run R.

If you don't want to change your path you can use Rgui.bat, Rterm.bat,
etc. in the batchfiles distribution at
   http://batchfiles.googlecode.com
Just put any of them that you wish to use on your path (they are self
contained Windows batch files, i.e. with no dependencies) and then
when you invoke any of them they will look up R in the registry and
run the corresponding command.

Thanks for suggestion.

It was indeed a path problem. 
I move R into a directory without spaces and added the directory RHOME\bin
in the Path environment variable.

All sorted.
