Hey,
I?m a newbie in R and have a big problem. I hope, I?m in the right mailinglist, if not, sorry for this.
I want to use R in my Java application and I found out, it should work with JRI. But it doesn?t.
I installed it and in the lib-directory of R there is a folder named "JRI". But I have to tell Eclipse
that the JRI exist but I don?t know how. I read help-files and so on, but I don?t understand.
Could you give me a simple instruction how to do this?
Very very thank you.

Greets Nadine

PS: To my person, I?m living in Bingen am Rhein (Germany) and studiing IT. My diploma project is an implementation
of the Transfer-Entropy in Java with the help of R (for calculations and graphics).

Please use the stats-rosuda-devel mailing list:

You may want to look at the archives, because roughly this question  
has been asked before.

            

      
      
      
    

        
Not really since I don't use Eclipse, but in general you just have to  
make sure that the necessary JAR files are on your class path, then  
you have to make sure Eclipse sets the java library path to the path  
with the jri.dll and finally PATH must contain the directory of R.dll.

(Also since this is a new project, you may consider using the high- 
level REngine API instead of the low-level JRI API. In addition,  
unless you have a specific reason for using JRI (R embedding) there  
are more simple solutions such as Rserve based on the same API - but  
the choice depends on what exactly your applications is doing)

Cheers,
Simon
