"R extension installed but not launching mac os x"

dolcos

I have installed R extension on Rapidminer Studio 6.1.0 on my MacOSX Retina Display with Yosemite 10.10.1.

My R version is 3.1.1.

But I could no see any perspective of R, and when I try to run R script I get this is the error:

"Process failed.

Could no initiate session with native R. Try using server. Reason: Could not initialize R via JRI. Reason: Unable to initialize R."

I have rJava and JavaGD working fine.

My bash profile:
export R_HOME=/Library/Frameworks/R.framework/Resources
export JAVA_HOME=$(/usr/libexec/java_home)

java_home: /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home

jri: /Library/Frameworks/R.framework/Versions/3.1/Resources/library/rJava/jri
