Ok. So I'm a little closer to figuring this thing out. I didn't realize I needed to run the javareconf command as root like so.
sudo R CMD javareconf JAVA_CPPFLAGS=-I/System/Library/Frameworks/JavaVM.framework/Headers I'm not getting the permission issue anymore but I'm still getting the segmentation fault error: => /Users/User/jgrLaunch ; exit; Loading preferences from /Users/User/.JGRprefsrc JGR R_HOME: /usr/local/Cellar/r/2.14.1/R.framework/Resources libroot: /usr/local/Cellar/r/2.14.1/R.framework/Versions/2.14/Resources/library/ Attempting to load jnilib: /usr/local/Cellar/r/2.14.1/R.framework/Versions/2.14/Resources/library/rJava/jri/libjri.jnilib Segmentation fault logout [Process completed] I also got this error from the R console: Feb 23 22:50:59 grizz R[46063] <Error>: kCGErrorInvalidConnection: CGSGetWindowTags: Invalid connection Feb 23 22:50:59 grizz R[46063] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
