I don't know how it'd work on Windows (though I suppose it should be similar) but on Linux, you basically need to * Put JRI.jar in your CLASSPATH * Put libjrio.so in your LD_LIBRARY_PATH (libR.so should also be in this PATH) * Set R_HOME to point to wherever you installed R Also if you only want to use R from Java (and don't need Java from R) then you should not need Rjava at all. The JRI source's should be sufficient. The CDK uses JRI to use R as a backend and you can take a look at the code that we use to interact with R.
