如何在R脚本中运行可执行文件.jar? [英] How can I run an executable .jar file in an R script?

问题描述

我正在从事一个相对较大的数据分析项目，在该项目中，我编写的R脚本是主要的可执行文件，并调用了所有其他代码.我不知道如何从我的R脚本中调用可执行文件.jar，但是我还没有看到这个问题在其他地方发布...这有可能吗?

I am working on a relatively large data analytics project in which an R script I wrote is the primary executable, calling all other bits of code. I can't figure out how to call an executable .jar from my R script, however and I haven't seen this question posted elsewhere... is this a possibility?

推荐答案

您可以使用rJava创建Java对象的实例.然后调用它的方法..

You can use rJava to create an instance of your java Object. Then you call its methods ..

library(rJava)
.jinit(PATH_TO_YOUR_JAR) # this starts the JVM
jobject <- .jnew("yourJavaClass")  ## call the constructor
.jcall(jobject ,"I",method="YOUR_METHOD") ## call a method
