Calling R function from C#

Question

Is there any way to call R function by using R.NET from C#?

I'm using Visual Studio 2017 and installed the latest version of R.NET. I had tried to use the codesearch from Google which using REngine.SetDllDirectory but Visual Studio show out an error:

<'REngine' does not contain a definition for 'SetDllDirectory'>.

Answer 1

Yes it is possible.

Some Gotchas that I found:

1) Be sure to modify your VS 2017 install to include the Data science and analytical applications. This will install the R server onto your machine.

2) Run in 64bit mode only.

3) Get the vanilla hello world sample going first.

Answer 2

Given there is a COM interface to R, you can use C#'s COM interop to control it.
