Hi, I am trying to integrate my Java program with R using rJava package. I want to execute the whole Java program from R. The main() method in my Java code calls all the other defined methods. So, I guess I have to call the main() method in .jcall.
An example Java code: *class A { public static int mySum(int x, int y) { return x+y; } public static void main (String[] arg) { System.out.println("The sum is " + mySum(2, 4)); } }* I can do the following to call the mySum() method: *.jcall(obj, "I", "mySum", as.integer(2), as.integer(4))* This will give the output *6*. But can some one explain me that how exactly I can execute this program to print *The sum is 6* from R? OR how can I call the main method? I am a beginner in R.
