For example, in this simple function where fun1 takes as input two numbers, adds them together and passes them to function 2 for printing the output. var1_in is local to each function, so is it OK to use the name var1_in in both functions, or is it better practice to call them different things?

fun1 <- function (var1_in, var2_in) {
    var3 = var1_in + var2_in
    fun2(var3)
    }

fun2 <- function (var1_in) {
    var4 = var1_in
    print(var4)
    }
