I sometimes teach a little R, and they might ask about static/lexical scope.
My short answer is normally that S uses static scoping and R uses
And most all modern languages uses lexical scoping.
So if they know Java, C, C# etc. then the scoping rules for R are the same.
I finally says that it is not a full answer but enough for most.
