请教多进程中调用R中的一段英文，没看明白

用了一个模块，叫statistics::R。现在要多进行中运行，模块有说明，是这样的，但是没有看太明白。
是要先写一个statistics-r.pl文件，再用statistics-r.pl start吗？
还是说只要程序里有 那段代码就行了。请高手解答一下。
EXECUTION FOR MULTIPLE PROCESS ^

The main pourpose of Statistics::R is to start a single R interpreter that hear multiple Perl process.

Note that to do that R and Perl need to be running with the same user/group level.

To start the Statistics::R bridge you can use the script statistics-r.pl: From your script you need to use the start_sharedR() option: Note that in the example above the method stopR() wasn't called, sine it will close the bridge.

那个文件一般安装到 site/bin 中了
