Hi  I want to develop application using R statistical computing and C# project. To have R Environment it is necessary to install the R-2.15.1-win.exe which will give me native DLLs installed with R environment. Is there any way to have R Environment without doing any setup. i tried the below ways to get it work, but not happening 1) i copied all the dlls which comes with R-2.15.1 setup from "C:\Program Files\R\R-2.15.1\bin" to my project location and uninstalled the "R". but when i tried to execute the code, it is throwing exception  public static void Main(string[] args) { REngine.SetDllDirectory(@"G:\R.Net\Binaries\x64"); REngine.CreateInstance("RDotNet"); REngine engine = REngine.GetInstanceFromID("RDotNet"); string stFirsValue = "30/40"; try { NumericVector x = engine.EagerEvaluate(stFirsValue).AsNumeric(); Console.Write("FirstValue: " + stFirsValue + " = " + x[0].ToString()); } catch (Exception objExp) { Console.Write(objExp.Message); } Console.Read(); }        REngine.CreateInstance("RDotNet");  the second line throw "Object reference not set to the instance of an object." 2) i copied the whole files from "C:\Program Files\R\R-2.15.1" which include all bin and lib files to my location and used that path for REngine.SetDllDirectory method. but still it was not working. how can do a manual installation, without running any setup. and create R environment into my project. so that i communicate with "R". registering R's COM DLL directly and start using them. please suggest  thanks in advance sendil  

Hi Sendil,
I have a similar requirement and exploring Rdot net as an option. I am very new to RdotNetect and struggling to get some know hows to build my C# proj.

I need to call R scripts from my C#/ASP.net page connected to ms sql server via RDotNet library and build a dashboard for my application. I am looking for some step by step guidance to achieve the same. I have tried to refer the articles available on internet but somehow, did not get the correct path. please help me with some suggestions.
Sincere thanks in advance
