Hi. I am a beginner. What is the difference between: x<-2 and x=2
It depends on the context. "x <- 2" always assigns the value 2 to the variable named x. Typed as an isolated command, that's what "x = 2" does too. However, when used as an argument to a function, e.g. f(x = 2), it associates the value 2 to the *argument* matched by x in the function call. This is occasionally confusing, so many people recommend that you always use "x <- 2" when you mean to do an assignment, and reserve the use of "=" for function arguments.
