C# - R interface

Question

I need to interface R to some C# application. I installed rscproxy_1.3 and R_Scilab_DCOM3.0-1B5 added COM references to the STATCONNECTORCLNTLib, StatConnectorCommonLib and STATCONNECTORSRVLib but I still cannot get it working.

When I run following test program:

using System; using System.Collections.Generic; using System.Linq; using System.Text;  //COM references using STATCONNECTORCLNTLib; using StatConnectorCommonLib; using STATCONNECTORSRVLib;  namespace R_TESTING {     class Program     {         static void Main(string[] args)         {             StatConnector sc1 = new STATCONNECTORSRVLib.StatConnectorClass();                      sc1.Init("R");         }     } } 

I get this exception:

Unhandled Exception: System.Runtime.InteropServices.COMException: Exception from HRESULT: 0x80040013    at STATCONNECTORSRVLib.StatConnectorClass.Init(String bstrConnectorName) 

Thanks in advance.

UPDATE: Ok, still no luck. I will try to explain what I did so far.

Installed R-2.12.2-win.exe from rproject to the C:\Program Files\R\R-2.12.2

Downloaded rscproxy_1.3-1.zip and copy/pasted it to the C:\Program Files\R\R-2.12.2\library

Installed R_Scilab_DCOM3.0-1B5.exe to the C:\Program Files (x86)\R\(D)COM Server

With Scilab comes a basic test. I tried to run it but I got following error:

Loading StatConnector Server... Done Initializing R...Function call failed Code: -2147221485 Text: installation problem: unable to load connector Releasing StatConnector Server...Done

Than I looked in the PATH/System Variables and found no path/R_HOME/R_USER info. Also, I couldn't find anything R related in the registry.

I guess I am doing something terribly wrong, so I desperately need help from you guys.

Answer 1

You can have a look at R.NET, for another approach...

Answer 2

Ok, I solved it finally. The problem is that R (D)Com doesn't work with current version of R. I installed 2.11.1 and it worked out of box.

Thanks a lot.
