我可以在不安装R的情况下使用R.Net

Question

I am building an application within C# and I want to use some of the R libraries within this application. I am using R.Net to do this.

However, I will deploy this software to users that may not have R downloaded on there computers. Is there any way that I can use the R dll so that the users can run my application without having to install R onto there machines?

Many thanks

While this question is rather old, maybe this elaboration on Hackerman's answer will still help someone:

You do not have to have R installed properly on your computer and you also do not have to have any registry entries for R if you want to use R.NET. However, R.NET still needs to access the native DLLs found in ...\\R\\bin\\i386 and the contents of ...\\R\\library.

Assuming your R files are located at C:\\Program Files, setting the paths to ...\\R\\bin\\i386 and ...\\R\\library works as follows:

REngine.SetEnvironmentVariables(@"C:\Program Files\R\bin\i386", @"C:\Program Files\R");

You can then set up an REngine using:

REngine engine = REngine.GetInstance();

This works using R.NET v1.7 and R v3.4.2 (32bit).
