In the OSGi v4.2 specification, the unified standard of remote invocation is defined, which further deepens the modular idea. As one of these implementations, R-OSGI provides a Service-oriented remote invocation component that allows us to easily implement the invocation of two OSGi Service in different geographies. This paper introduces the implementation of traditional OSGi application and R-osgi, and expounds the implementation of R-OSGI for OSGi specification. Then through a simple function to achieve by the shallow into ...

R: It's not a real language. Part of the reason we learn about R is that it's not really a programming language. John Cook, an R expert, said: "R is a statistical interactive environment, not a real programming language." It is more helpful to think of R as an interactive environment containing programming languages. "But as Bob Muenchen emphasizes, R is even harder for people who are proficient in SAS and SPSS data tools." About R for analyst ...
