Rmath-Java

Rmath-Java is a Java wrapper of the Rmath library from R, which contains functions related to statistical distributions.

Dependency

This library uses JNA to call native code in Rmath. See the next section for download link of JNA.

Getting Rmath-Java

Download

• JNA (4.2.0)
• Rmath-Java for Windows and 64-bit Linux. For other systems and architectures, the jar file can be built from source.

Build from source

To build Rmath-Java from source, one needs:

• GCC/Clang compiler
• JDK
• make

Then simply enter the source directory and type make.

Examples

For Java,

import statr.rmath.Rmath;

public class TestRmath {
    public static void main(String[] args) {
        System.out.println("dnorm(1.2, mu = 3.4, sd = 5.6) = " +
                           Rmath.dnorm(1.2, 3.4, 5.6));
    }
}

or in Scala,

import statr.rmath.Rmath

Rmath.dnorm(1.2, 3.4, 5.6)
