    I recently installed the R extension on a Mac.  I followed the onscreen instructions. The only thing I had to do that required a little "look up" on my part was editing my .profile text file.

    I still can't get it to work on my MacBook Air running OS X 10.10.2

    I had installed the R extension once before but never got it to work successfully.  I tried it again and here are my steps.

    1. Installed RapidMiner
    2. Installed R
    3. Installed RStudio
    4. Opened RStudio
    5. > install.packages(c(“rJava”, “JavaGD”))
        > library(rJava)
        > library(JavaGD)
    6. opened Terminal
    7. $ cd ~/
        $ touch .bash_profile
        $ open -e .bash_profile
    8. added the following lines to .bash_profile
        export R_HOME=/Library/Frameworks/R.framework/Resources
        export JAVA_HOME=$(/usr/libexec/java_home)
                      --- or ---
        export JAVA_HOME=$(/usr/libexec/java_home -v 1.6)
    9. $ . .bash_profile
    10. checked my work by
        $ echo $R_HOME
    /Library/Frameworks/R.framework/Resources
        $ echo $JAVA_HOME
    /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
          <<<I also tried version 1.7>>>
    11. started RapidMiner and the R console did not show up
    12. removed the R extension
    13. shut down and restarted RapidMiner
    14. installed the R extension
    15. went into preferences, hit the R tab
    16. set the JRI library files to
              /Library/Frameworks/R.framework/Versions/3.1/Resources/library/rJava/jri/libjri.jnilib
    15. shut down and restarted RapidMiner
    16. still no R console

    Hi,

    sadly installing the old R extension can be a pain or simply refuse to work for some reasons. I'm afraid I don't know hot to help you with your exact problem right now, but we have been working on something which will make using R (and getting it to work in the first place) significantly easier, and it's not far away.
    All I can say right now is: stay tuned for the next Studio release coming very soon ;)

    Regards,
    Marco

    Hi,

    the new Studio release 6.4.0 is now live. I suggest downloading the all new OSX application and then searching our Marketplace for "R Scripting". This is the new extension which allows you to integrate R scripts into your process workflow without much hassle.
    The old R Extension is no longer supported going forward from Studio 6.4 and will only remain for Studio 6.3 and earlier.

    Regards,
    Marco
