我在OS X 10.5上运行R 3.2.4，并安装了多个Java。我目前使用JDK 7作为默认安装。使用R CMD javareconf，所有内容都会正确配置：
guhar@NCATS-1850784-M:~/src/cdkr [master*]$ R CMD javareconf JAVA_CPPFLAGS='-I/Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home/include/'

然后我安装rJava 0.98并且没有报告错误。但是，当我启动R并使用rJava时，它表示java.version系统属性（表示JRE版本）为1.6，即使JAVA_HOME设置为我的JDK 7安装：< / p>
> library(rJava)
> .jinit()
> .jcall("java/lang/System","S","getProperty","java.version")
[1] "1.6.0_65"
我需要在rJava方面设置一些内容才能识别我的JAVA_HOME设置吗？或者这是否需要在OS X环境中设置？
