[R] Calling a source file from R to C#

[Ashis Deb]

I had this code like :--


using System.Text;
using RDotNet;
using RDotNet.NativeLibrary;
using Stats;


namespace ConsoleApplication1
{

    class Program
    {
        static void Main(string[] args)
        {


            string rhome =
System.Environment.GetEnvironmentVariable("R_HOME");
            if (string.IsNullOrEmpty(rhome))
                rhome = @"C:\Program Files (x86)\R\R-2.11.1";

            System.Environment.SetEnvironmentVariable("R_HOME", rhome);
            System.Environment.SetEnvironmentVariable("PATH",
System.Environment.GetEnvironmentVariable("PATH") + ";" + rhome +
@"\bin\i386");

            REngine.SetDllDirectory(@"C:\Program Files
(x86)\R\R-2.11.1\bin");

            using (REngine engine = REngine.CreateInstance("RDotNet"))
            {

                  engine.Initialize();

                  REngine R = REngine.GetInstanceFromID("RDotNet");

                  engine.Evaluate("source('D:/n1.R')");   <<-------  here
i  m  calling  a  r script   contain  a  function  .


                Console.ReadKey();

            }
        }
    }
}








My  function  looks like :---




fun<-function(x,y)
{

z=x*y

return(z)

}




But  i  getting  the  error like  :-   Parse exception  was  unhanded  &
in the  command  line its showing like :----

Error in source :-<"D:/n1.R") : D:/n1.R:1:1: unexpected ')'  1: )




I  am  using  R 2.11.1  and  vs2010 .



Does anybody  have any  solution for this ??  ,please help me out with
this  issue.
