问题
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.
回答1:
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...
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):
