我需要从Java应用程序运行R代码. R Server安装在远程设备上.我找不到有关R的Java连接器的任何信息.也许我只是暴露了我的无知，但是任何暗示可以做到这一点的方法都将不胜感激.

I need to run R Code from Java application. The R Server is installed on the remote box. I failed to find any information on Java connector for R. Maybe I am just exposing my ignorance, but any hints how this can be done would be appreciated.

推荐答案

Rserve源软件包中有示例Java客户端.我会指向SVN浏览器，但我永远不记得Simon的RForge是否具有SVN浏览器...

There are sample Java clients in the Rserve source packages. I'd point to a SVN browser but I can never remember if Simon's RForge has a SVN browser...

这是我在Debian中维护的旧软件包中的客户端的树状视图(但您可能希望直接从RForge永久发布的1.7.0版):

Here is a tree view of the client from the older package I maintain in Debian (but you probably want the eternally-unreleased 1.7.0 directly from RForge):
