Hi John

As Matt said I think your problem is Windows Path.

I have Kepler 1.0 and later I installed a more recent R  version (R 2.12.1)
and I can run well Kepler demos with R actors.

Try to call R in a command line (in start make cmd) and execute “set”
command to see the environment that Kepler will use when it start.

You should see in Path variable something like Path=C:\Program Files\......;

.;C:\Program Files\R\R-2.12.1\bin;

;
..

I am hoping to  help you.

Hi John,

I think you missed option 4:

   - The list is filled with busy people and it slipped through the cracks.
Sorry.

But, to the point of your questions:

1) When we first shipped Kepler 1.0.0, there were two windows installers:
one with R included, and one without to keep the download sizes lower.  You
have the one without.  We don't ship the one with R because of the licensing
implications of mixing GPL code with our BSD licensed software.  You can of
course install it separately as you have done.

2) For R to work in Kepler, Kepler must be able to find it on the path.
Your approach should work, but the Windows path is a tricky thing.  Have you
verified that you can run R from the command line and its found on the path?
I suspect you have a problem with the space in the path to R -- maybe try
quoting it, or try it with the 'Program Files' path component replaced with
'Progra~1'.  In any case, if Kepler can find R 2.6.2 on the path, it should
work.

On a side note, why are you using Kepler 1.0.0?  Kepler 2 has been out for a
while, has a lot of improvements and bug fixes over Kepler 1.0.0, and is
supported.  There are known problems with the R support in Kepler 1.0.0 that
were fixed in Kepler 2.  Can you upgrade?

Hello dear Kepler users,

I got no answer to the 2011-01-11 mail below.

Several possible explanations:

- I am the only Windows Kepler user !

- I am the only Windows Kepler user trying to install R

- This mailing list is not adequate for such a question

Could somebody give me a hint ?

Yours sincerely,

Jean Johner

Objet : R installation for Kepler 1.0.0 on Windows

Hello,

I am new to Kepler. Sorry if my problem has been overposted.

I first installed Kepler 1.0.0 on Windows XP from
https://kepler-project.org/users/downloads.

After opening the 00-StatisticalSummary.xml workflow in C:\Program
Files\Kepler-1.0.0\demos\getting-started and pressing the Run button, I get
the following message : 

« There has been a problem launching the R application !

It may be that R is not installed on your system, or it

may not be on your path and cannot be located by Kepler.

Please make sure R is installed and the R command line

executable is in the path. For more information, see 

section 8.2.2 of the KeplerUser Manual .»

Reading section 2.2.2 of the UserManual, we see :

5. Choose the packs to install: Base, R (2.6.2), Sources. The Base pack is
required.

The Sources pack contains the application source code which, if installed,
allows

you to build Kepler yourself. We recommend that you select all three (the

default), which installs the Kepler software and source and R on your
system.

Unfortunately, only the Base and Sources packages are proposed in
kepler-win-1.0.0.exe.

So, I installed R-2.6.2 independently, added “C:\Program
Files\R\R-2.6.2\bin” to the Windows path and reinstalled Kepler.

But the above message is still there in the same conditions.

Questions :

1/ why is the R (2.6.2) package absent from the installation exe

2/ what is wrong in the above explained work-around.

Best regards.

Jean Johner
