Setting up Java R Interface (JRI) on Windows

I have followed guides on the web and looked at questions on stackoverflow but I am still not able to set up JRI on Windows.

Here are the steps I have taken:

1) Install R

2) Execute install.packages("rJava") in R to install rJava

3) Create a R_HOME system variable with value C:\Program Files\R\R-3.1.2

4) Add the following to my PATH variable: C:\Program Files\R\R-3.1.2\bin\x64;C:\Users\USERNAME\Documents\R\win-library\3.1\rJava\jri\x64

5) Added the JRI.jar (located in C:\Users\USERNAME\Documents\R\win-library\3.1\rJava\jri) as a dependency in IntelliJ

6) Set the VM options in IntelliJ to -Djava.library.path=C:\Users\USERNAME\Documents\R\win-library\3.1\rJava\jri\x64

7) Start R and execute library("rJava")

8) Run my program to test if everything is set up

Get the following error:

#

If I remove the VM option so that java.library.path isn't specified then I get the following error:

Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.

Solution

How you instantiating Rengine?

It should be something like this:

Rengine rengine = new Rengine(args, false, null);

where, the args could be from your main method.

Let me know if this works!
