"R Extension doesn't work for me"

I just installed the R extension, configured it according it to all steps in the "Installation Guide", and restarted. However I still can't see the new "R" perspective.  RapidMiner provides no clue what the actual issues is. Anyone an idea? I am running on a Mac ("Snow Leopard").

    Hi Dirk,
    so the installation guide poped up after the restart? Then at least the java part of the extension is loaded.
    The problem must then lie in the connection to the native libraries of R. Are you sure you have met all prerequisits? Is your java directory configured correctly, path variables updated? And finally does the architecture of the used Java Runtime Enviroment match the R installation?

    If you have checked all this, please post the complete console output of RapidMiner during start up, when you start it from a console.

    Hi Dirk,

    have you set the R_HOME environment variable properly?

    works fine for me.

    I also had problems on Mac OS X Leopard. The solution was to add the following line to the RapidMinerGUI script with which I start RapidMiner:
    export R_HOME=/Library/Frameworks/R.framework/Versions/2.11/Resources

    I think this R_HOME variable is not in the Installation Guide, I just found out based on the console logs. Also the filename for the JRI is different, in my case libjri.jnilib, maybe these should be added to the guide.

    thanks for pointing this out - we will add those points to the guide (Sebastian?).

    actually the lib name might differ on different Operating Systems, but should be imported correctly from java automatically. Of course it's missleading, I will add these to the installation guide.

    Thank you all for this information.

    By the way:
