  Thank you very much for your help. It did work.  So here is the code that
I've used case anybody else is seaching for an answer to this
problem :


System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = "E:/R/bin/Rscript.exe";
proc.StartInfo.WorkingDirectory = "E:/R/bin/";
proc.StartInfo.Arguments = "E:/R/bin/test.r";
proc.StartInfo.UseShellExecute = true;
proc.StartInfo.RedirectStandardOutput = false;
proc.Start();


         Thanks again for your help, good luck.

                       Alex
