Call R function from Java

Dear All,

  I need to call R functions from Java, I've read on the internet  
about JRI but there are no exemples, neither tutorials.

There are some basic examples in JRI/examples

  I'm beginner in Java and in R,

JRI is a low-level interface, so may need to learn more about R.  
However, the experimental JRI 0.3 is getting some higher-level API  
and is available from http://www.rosuda.org/R/nightly/

Cheers,
Simon
