Execute local R script

Aug 20, 2013 at 6:38 AM
I'm looking to use R.NET to execute an existing R script but haven't had success. Is this actually possible? I've run the example code successfully, so my basic setup is ok.

My code looks like the following:
      static void RTest()
         var envPath = Environment.GetEnvironmentVariable("PATH");
         var rBinPath = System.Environment.Is64BitProcess ? @"C:\Program Files\R\R-3.0.1\bin\x64" : @"C:\Program Files\R\R-3.0.1\bin\i386";
         Environment.SetEnvironmentVariable("PATH", envPath + Path.PathSeparator + rBinPath);

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

            using( var fs = File.OpenRead(@"C:\R-scripts\r-test.R") )
Which I'm running in a console app for testing (eventually I want to have it run server-side in a web app).

The r-test.R script works when run in RStudio so there's no problem there and should result in writing a csv file to disk. I do see some 'Loading required package' messages being output to the console so something is working but the resultant csv file does not appear.

No need for you to read the file in C#
