    R.framework was installed to:
      #{opt_prefix}/R.framework

    To use this Framework with IDEs such as RStudio, it must be linked
    to the standard OS X location:
      sudo ln -s "#{opt_prefix}/R.framework" /Library/Frameworks

    To enable rJava support, run the following command:
      R CMD javareconf JAVA_CPPFLAGS=-I/System/Library/Frameworks/JavaVM.framework/Headers
