I want to visualize some of my statistical caluclations in Ruby.
My problem is, that I can\'t find the right gem for that.
rsruby doesn\'t seem to be up-to-date
As @Hansi mentioned, RServe is the best way I've found to run R remotely. If you're using Ruby from a web-context especially, RServe can offer some nice benefits.
Best of all (in my mind), you don't get locked into any one programming framework, as there are RServe clients for a variety of languages including Java and C++. When using web-accessible platforms, you can even keep Rserve running on a separate host and route traffic over TCP/IP for added security.
