I do not see the problem.
In base R
Min <- min(var, na.rm=T)
Max <- max(var, na.rm=T)
Span <- c(Min, Max)
Is the same output as
Span <- range(var, na.rm=T)
diff(range(var, na.rm=T)) returns Max - Min
range() returns a vector with two values, the minimum and the maximum.
What should the function "span" do that is not already done?

I often need to determine the span of the x-variable in a graphic.
This is easy to determine with:
diff(range(VAR, na.rm=T))
I am not aware of any function in base R that accomplishes this and "span" is
not taken.
Would it be possible to add such a function? Not a major addition but often
useful.
