Integrated R.Net within your ASP.Net MVC applicaiton

R is a programming language used for statistical computing. For business intelligence, R is very useful for prediction marketing. To better integrating R into Microsoft .Net system, there is one tool named R.Net. You can use NuGet to install R.Net to your .net project. The latest version of R.Net is 1.6.5. You can use the following command to install the latest R.Net:
Install-Package R.NET.Community
Note R.Net didn't set the environment variable correctly. So the first issue you suffered for R.Net would be package installation.

REngine r = REngine.GetInstance();
r.Evaluate("library(RODBC)");

An unhandled exception of type 'RDotNet.EvaluationException' occurred in RDotNet.dll
Additional information: Error: package or namespace load failed for 'RODBC'

This is happened because R.net can't find r.dll as the Path doesn't included. To set the correct Path under windows 10, click on windows button, choose Settings, click on System, choose About from the left menu, scroll down to the bottom, click on System Info, choose Advanced System Setting from the left menu, choose the Tab of Advanced, click on Environment Variables button, then click on Edit button, click on New button, add following path:
C:\\Program Files\\R\\R-3.3.1\\bin\\i386
After this, restart windows 10, you should resolve this issue. Note other resources prefer to add more paths such as library, it's wrong!!! It will affect some packages installation.
