What is "The R Interpreter" setting in IntelliJ IDEA?

intellij-idea, r

Solution

Sorry I'm a so newbie of IntelliJ IDEA. And I got the answer. The R Interpreter means the x64/R.exe file in my R installation folder. But still don't know how to set the "Sources" in that same page.

Problem

My OS is Windows 7. I have installed "IntelliJ IDEA 2016.2.5", and "R x64 3.1.2". I'm going to do some R language coding in IntelliJ IDEA. So I installed the plugin "IntelliJ plugin for the R language". Then I'm blocked by its setting, at File->Settings->Other Settings->The R Interpreter. I have no idea of what is "R Interpreter". Which file is it?
