An example of using rJava
...ed a few private emails asking for some simple
demonstration of calling Java code from R using the rJava package
(which can be installed directly inside R). Here is one example for
convolving two vectors (an example in the R manual about linking C with
R).
First write a Java program
public class my_convolve
{
public static double[] convolve(double[] a, double[] b)
{
int n1 = a.length;
int n2 = b.length;
int n3 = n1+n1-1;
double[] c = new double[n3];
for(int i=0; i<n1; i++)
for(int j=0; j<n2; j++) c[i+j] +=...
