Integrate Java and R – Just in a minute

Creating a rich statistical application can become very handy and useful once you integrate Java with R.
Integration needs following to be installed already:

  1. JDK 1.5 or above ( I tried with 1.6 )
  2. R – can be downloaded from CRAN
  3. R_HOME environment variable is set.

Here is how you can integrate and configure your java to work with R:

  1. From R install the rJava package ( can be easily be done with install command in R ). The latest rJava contains JRI implicit so no need to download it manually.
  2. Go to the download directory of R  and you can see the rJava directory, and inside that there will be JRI directory include that in your java.library.path

And you are done 🙂
Enjoy !
