The zip file actually works fine for me. Anyhow, here is the code snippet that you need:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using Interop.STATCONNECTORSRVLib; namespace RFromCsharp { class RConnector { private StatConnectorClass rdcom = null; private string rcmd; public StatConnectorClass RConnection { get { return rdcom; } set { rdcom = value; } } private bool initR() { try { rdcom = new StatConnectorClass(); rdcom.Init("R"); return true; } catch(Exception e) { string errmsg = "R Init failed: " + rdcom.GetErrorText() + " Other: " +e.Message.ToString(); Console.WriteLine(errmsg); return false; } } private bool loadR(string table, string filename, bool stripwhite, bool header, string separator) { try { rcmd = table.ToString() + "<-read.delim('" + filename.ToString() + "',strip.white=" + stripwhite.ToString().ToUpper() + ",header=" + header.ToString().ToUpper() + ",sep='" + separator.ToString() + "')"; rdcom.EvaluateNoReturn(rcmd); return true; } catch(Exception e) { string errmsg = rcmd.ToString() + " " + rdcom.GetErrorText() + " Other:" + e.Message.ToString(); Console.WriteLine(errmsg); return false; } } private bool closeR() { try { rcmd = "graphics.off()"; rdcom.EvaluateNoReturn(rcmd); rcmd = "rm(list=ls(all=TRUE))"; rdcom.EvaluateNoReturn(rcmd); rdcom.Close(); return true; } catch(Exception e) { string errmsg = "R Close failed: " + rdcom.GetErrorText() + " Other: " + e.Message.ToString(); Console.WriteLine(errmsg); return false; } } static void Main(string[] args) { RConnector conn = new RConnector(); // Initialize the instance to be used with R conn.initR(); // create an R variable named abc and assign it the value of 5 conn.RConnection.SetSymbol("abc", 5); // Retrieve the value of the R variable named abc and assign that value to the F# value valueForabc var valueForabc = conn.RConnection.GetSymbol("abc"); // Evaluate an expression in R and assign that value to an F# value aTestEvaluation var aTestEvaluation = conn.RConnection.Evaluate("8 * sin(4)"); // Close the R connection conn.closeR(); Console.BackgroundColor = ConsoleColor.Gray; Console.ForegroundColor = ConsoleColor.Blue; Console.WriteLine("Value of abc:" + valueForabc); Console.WriteLine("Value of 8 * sin(4):" + aTestEvaluation); Console.WriteLine("Press any key to continue ..."); Console.ReadKey(); //----------------------------- } } } You would also need to reference the Interop.STATCONNECTORSRVLib.dll assembly.
