That said, R isn’t entirely on its own. I'm not familiar with any other language that allows the right-assignment semantics.

11. Is R an interpreted or compiled programming language?

    stackoverflow.com/questions/1677021

    You can build a compiler or interpreter for any programming language. In general, the language itself is not compiled or interpreted. So, R could be either interpreted or compiled. Nonetheless, in the most common implementation, R is interpreted.
